Modern leather-working tools

Leather is a durable and flexible material created by the tanning of putrescible animal rawhide and skin, often cattle hide. It can be produced through manufacturing processes ranging from cottage industry to heavy industry.

Forms[link]

Several tanning processes transform hides and skins into leather:

• Vegetable-tanned leather is tanned using tannin and other ingredients found in vegetable matter, such as tree bark prepared in bark mills, and other similar sources. It is supple and brown in color, with the exact shade depending on the mix of chemicals and the color of the skin. It is the only form of leather suitable for use in leather carving or stamping. Vegetable-tanned leather is not stable in water; it tends to discolor, and if left to soak and then dry it will shrink and become less supple, and harder. In hot water, it will shrink drastically and partly gelatinize, becoming rigid and eventually brittle. Boiled leather is an example of this, where the leather has been hardened by being immersed in hot water, or in boiled wax or similar substances. Historically, it was occasionally used as armor after hardening, and it has also been used for book binding.
• Chrome-tanned leather, invented in 1858, is tanned using chromium sulfate and other salts of chromium. It is more supple and pliable than vegetable-tanned leather and does not discolor or lose shape as drastically in water as vegetable-tanned. It is also known as wet-blue for its color derived from the chromium. More esoteric colors are possible using chrome tanning.
• Aldehyde-tanned leather is tanned using glutaraldehyde or oxazolidine compounds. This is the leather that most tanners refer to as wet-white leather due to its pale cream or white color. It is the main type of "chrome-free" leather, often seen in automobiles and shoes for infants.
  • Formaldehyde tanning (being phased out due to its danger to workers and the sensitivity of many people to formaldehyde) is another method of aldehyde tanning. Brain-tanned leathers fall into this category and are exceptionally water absorbent.
    • Brain tanned leathers are made by a labor-intensive process which uses emulsified oils, often those of animal brains. They are known for their exceptional softness and their ability to be washed.
  • Chamois leather also falls into the category of aldehyde tanning and like brain tanning produces a highly water absorbent leather. Chamois leather is made by using oils (traditionally cod oil) that oxidize easily to produce the aldehydes that tan the leather to make the fabric the color it is.
  • Rose tanned leather is a variation of vegetable oil tanning and brain tanning, where pure rose otto replaces the vegetable oil and emulsified oils. It has been called the most valuable leather on earth but this is mostly due to the high cost of rose otto and its labor intensive tanning process.^[1]

• Synthetic-tanned leather is tanned using aromatic polymers such as the Novolac or Neradol types (syntans, contraction for synthetic tannins). This leather is white in color and was invented when vegetable tannins were in short supply during the Second World War. Melamine and other amino-functional resins fall into this category as well, and they provide the filling that modern leathers often require. Urea-formaldehyde resins were also used in this tanning method until dissatisfaction about the formation of free formaldehyde was realized.
• Alum-tawed leather is transformed using aluminium salts mixed with a variety of binders and protein sources, such as flour and egg yolk. Purists^[who?] argue that alum-tawed leather is technically not tanned^{[citation needed]}, as the resulting material will rot in water. Very light shades of leather are possible using this process, but the resulting material is not as supple as vegetable-tanned leather.^[2]
• Rawhide is made by scraping the skin thin, soaking it in lime, and then stretching it while it dries. Like alum-tawing, rawhide is not technically "leather"^{[citation needed]}, but is usually lumped in with the other forms. Rawhide is stiffer and more brittle than other forms of leather; it's primarily found in uses such as drum heads where it does not need to flex significantly; it is also cut up into cords for use in lacing or stitching and for making many varieties of dog chews.

Leather—usually vegetable-tanned—can be oiled to improve its water resistance. This supplements the natural oils remaining in the leather itself, which can be washed out through repeated exposure to water. Frequent oiling of leather, with mink oil, neatsfoot oil, or a similar material keeps it supple and improves its lifespan dramatically.

Leather with the hair still attached is called hair-on.

Types[link]

In general, leather is sold in four forms:

• Full-grain leather refers to hides that have not been sanded, buffed, or snuffed (as opposed to top-grain or corrected leather) to remove imperfections (or natural marks) on the surface of the hide. The grain remains allowing the fiber strength and durability. The grain also has breathability, resulting in less moisture from prolonged contact. Rather than wearing out, it will develop a patina over time. High quality leather furniture and footwear are often made from full-grain leather. Full-grain leathers are typically available in two finish types: aniline and semi-aniline.

• Top-grain(Most common type used in upper end leather products)leather is the second-highest quality. It's had the "split" layer separated away, making it thinner and more pliable than full-grain. Its surface has been sanded and a finish coat added to the surface which results in a colder, plastic feel with less breathability, and will not develop a natural patina. It is typically less expensive and has greater resistance to stains than full-grain leather, so long as the finish remains unbroken.

• Corrected-grain leather is any leather that has had an artificial grain applied to its surface. The hides used to create corrected leather do not meet the standards for use in creating vegetable-tanned or aniline leather. The imperfections are corrected or sanded off, and an artificial grain impressed into the surface and dressed with stain or dyes. Most corrected-grain leather is used to make pigmented leather as the solid pigment helps hide the corrections or imperfections. Corrected grain leathers can mainly be bought as two finish types: semi-aniline and pigmented.

• Split leather is leather created from the fibrous part of the hide left once the top-grain of the rawhide has been separated from the hide. During the splitting operation, the top grain and drop split are separated. The drop split can be further split (thickness allowing) into a middle split and a flesh split. In very thick hides, the middle split can be separated into multiple layers until the thickness prevents further splitting. Split leather then has an artificial layer applied to the surface of the split and is embossed with a leather grain (bycast leather). Splits are also used to create suede. The strongest suedes are usually made from grain splits (that have the grain completely removed) or from the flesh split that has been shaved to the correct thickness. Suede is "fuzzy" on both sides. Manufacturers use a variety of techniques to make suede from full-grain. A reversed suede is a grained leather that has been designed into the leather article with the grain facing away from the visible surface. It is not considered to be a true form of suede.^[3]

Less-common leathers include:

• Buckskin or brained leather is a tanning process that uses animal brains or other fatty materials to alter the leather. The resulting supple, suede-like hide is usually smoked heavily to prevent it from rotting.

• Patent leather is leather that has been given a high-gloss finish. The original process was developed in Newark, New Jersey, by inventor Seth Boyden in 1818. Patent leather usually has a plastic coating.

• Shagreen is also known as stingray skin/leather. Applications used in furniture production date as far back as the art deco period. The word "shagreen" originates from France.

• Vachetta leather is used in the trimmings of luggage and handbags. The leather is left untreated and is therefore susceptible to water and stains. Sunlight will cause the natural leather to darken in shade, called a patina.

• Slink is leather made from the skin of unborn calves. It is particularly soft and is valued for use in making gloves.

• Deerskin is a tough leather, possibly due to the animal's adaptations to its thorny and thicket-filled habitats.^{[citation needed]} Deerskin has been used by many societies, including indigenous Americans. Most modern deerskin is no longer procured from the wild, with deer farms breeding the animals specifically for the purpose of their skins. Large quantities are still tanned from wild deer hides in historic tanning towns such as Gloversville and Johnstown in upstate New York. Deerskin is used in jackets and overcoats, martial arts equipment such as kendo and bogu, as well as personal accessories such as handbags and wallets.

• Nubuck is top-grain cattle hide leather that has been sanded or buffed on the grain side, or outside, to give a slight nap of short protein fibers, producing a velvet-like surface.

There are two other types of leather commonly used in specialty products, such as briefcases, wallets, and luggage:

• Belting leather is a full-grain leather that was originally used in driving pulley belts and other machinery. It is found on the surface of briefcases, portfolios, and wallets, and can be identified by its thick, firm feel and smooth finish. Belting leather is generally a heavy-weight of full-grain, vegetable-tanned leather.

• Napa leather is chrome-tanned and is soft and supple. It is commonly found in wallets, toiletry kits, and other personal leather goods.

The following are not "true" leathers, but contain leather material. Depending on jurisdiction, they may still be labeled as "Genuine Leather":

• Bonded leather, or "reconstituted Leather", is composed of 90% to 100% leather fibers (often scrap from leather tanneries or leather workshops) bonded together with latex binders to create a look and feel similar to that of leather at a fraction of the cost. This bonded leather is not as durable as other leathers and is recommended for use only if the product will be used infrequently. Bonded leather upholstery is a vinyl upholstery that contains about 17% leather fiber in its backing material. The vinyl is stamped to give it a leather-like texture. Bonded leather upholstery is durable and its manufacturing process is more environmentally-friendly than leather production.

• Bycast leather is a split leather with a layer of polyurethane applied to the surface and then embossed. Bycast was originally made for the shoe industry and recently was adopted by the furniture industry. The original formula created by Bayer was strong but expensive. Most of the bycast used today is a very strong and durable product. The result is a slightly stiffer product that is cheaper than top grain leather but has a much more consistent texture and is easier to clean and maintain.

From other animals[link]

Today most leather is made of cattle skin but many exceptions exist. Lamb and deerskin are used for soft leather in more expensive apparel. Deer and elkskin are widely used in work gloves and indoor shoes. Pigskin is used in apparel and on seats of saddles. Buffalo, goats, alligators, dogs, snakes, ostriches, kangaroos, oxen, and yaks may also be used for leather.

Kangaroo skin is used to make items which need to be strong but flexible—it is the material most commonly used in bullwhips. Kangaroo leather is favored by some motorcyclists for use in motorcycle leathers specifically because of its light weight and abrasion resistance.^[4] Kangaroo leather is also used for falconry jesses and soccer footwear.^[5]

At different times in history, leather made from more exotic skins has been considered desirable. For this reason certain species of snakes and crocodiles have been hunted.^{[citation needed]}

Although originally raised for their feathers in the 19th century, ostriches are now more popular for both meat and leather.^[6] There are different processes to produce different finishes for many applications, i.e., upholstery, footwear, automotive products, accessories, and clothing. Ostrich leather is currently used by many major fashion houses such as Hermès, Prada, Gucci, and Louis Vuitton. Ostrich leather has a characteristic "goose bump" look because of the large follicles from which the feathers grew.

In Thailand sting ray leather is used in wallets and belts. Sting ray leather is tough and durable. The leather is often dyed black and covered with tiny round bumps in the natural pattern of the back ridge of an animal. These bumps are then usually dyed white to highlight the decoration. Sting ray leather is also used as grips on Chinese swords and Japanese katanas.

Production processes[link]

The leather manufacturing process is divided into three fundamental sub-processes: preparatory stages, tanning, and crusting. All true leathers will undergo these sub-processes. A further sub-process, surface coating, can be added into the leather process sequence, but not all leathers receive surface treatment. Since many types of leather exist, it is difficult to create a list of operations that all leathers must undergo.

The preparatory stages are when the hide/skin is prepared for tanning. Preparatory stages may include: preservation, soaking, liming, unhairing, fleshing, splitting, reliming, deliming, bating, degreasing, frizing, bleaching, pickling, and depickling.

Tanning is the process which converts the protein of the raw hide or skin into a stable material which will not putrefy and is suitable for a wide variety of end applications. The principal difference between raw hides and tanned hides is that raw hides dry out to form a hard inflexible material that when re-wetted (or wetted back) putrefy, while tanned material dries out to a flexible form that does not become putrid when wetted back. Many different tanning methods and materials can be used; the choice is ultimately dependent on the end application of the leather. The most commonly used tanning material is chromium, which leaves the leather, once tanned, a pale blue color (due to the chromium); this product is commonly called "wet blue". The hides once they have finished pickling will typically be between pH 2.8 and 3.2.^{[citation needed]} At this point, the hides would be loaded in a drum and immersed in a float containing the tanning liquor. The hides are allowed to soak (while the drum slowly rotates about its axle) and the tanning liquor slowly penetrates through the full substance of the hide. Regular checks will be made to see the penetration by cutting the cross-section of a hide and observing the degree of penetration. Once an even degree of penetration exists, the pH of the float is slowly raised in a process called basification. This basification process fixes the tanning material to the leather and the more tanning material fixed, the higher the hydrothermal stability and increased shrinkage temperature resistance of the leather. The pH of the leather when chrome tanned would typically finish somewhere between 3.8 and 4.2.^{[citation needed]}

Crusting is the process by which the hide/skin is thinned, retanned, and lubricated. Often a coloring operation is included in the crusting subprocess. The chemicals added during crusting must be fixed in place. The culmination of the crusting subprocess is the drying and softening operations. Crusting may include the following operations: wetting back, sammying, splitting, shaving, rechroming, neutralization, retanning, dyeing, fatliquoring, filling, stuffing, stripping, whitening, fixating, setting, drying, conditioning, milling, staking, and buffing.

For some leathers, a surface coating is applied. Tanners refer to this as finishing. Finishing operations may include: oiling, brushing, padding, impregnation, buffing, spraying, roller coating, curtain coating, polishing, plating, embossing, ironing, ironing/combing (for hair-on), glazing, and tumbling.

Environmental impact[link]

Leather is a product with some environmental impact, most notably due to:

• the impact of livestock
• the use of chemicals in the tanning process
• air pollution due to the transformation process (hydrogen sulfide during dehairing and ammonia during deliming, solvent vapors).
• Leather biodegrades slowly; it takes 25–40 years to decompose. However, vinyl and petro-chemical derived materials will take 500 or more years to break down and return to the earth.

One ton of hide or skin generally leads to the production of 20 to 80 m³ of wastewater including chromium levels of 100–400 mg/L, sulfide levels of 200–800 mg/L and high levels of fat and other solid wastes, as well as notable pathogen contamination. Pesticides are also often added for hide conservation during transport. With solid wastes representing up to 70% of the wet weight of the original hides, the tanning process comes at a considerable strain on water treatment installations.^[7]

Tanning is especially polluting in countries where environmental regulations are lax, such as in India, the world's third-largest producer and exporter of leather. To give an example of an efficient pollution prevention system, chromium loads per produced tonne are generally abated from 8 kg to 1.5 kg. VOC emissions are typically reduced from 30 kg/t to 2 kg/t in a properly managed facility. A review of the total pollution load decrease achievable according to the United Nations Industrial Development Organization^[8] posts precise data on the abatement achievable through industrially proven low-waste advanced methods, while noting that "even though the chrome pollution load can be decreased by 94% on introducing advanced technologies, the minimum residual load 0.15 kg/t raw hide can still cause difficulties when using landfills and composting sludge from wastewater treatment on account of the regulations currently in force in some countries."

In Kanpur, the self-proclaimed "Leather City of World" with 10,000 tanneries as of 2011 and a city of 3 million people on the banks of the river Ganges, pollution levels were so high that despite an industry crisis, the pollution control board has decided to seal 49 high-polluting tanneries out of 404 in July 2009.^[9] In 2003 for instance, the main tanneries' effluent disposal unit was dumping 22 tonnes of chromium-laden solid waste per day in the open.^[10] Scientists at the Central Leather Research Institute in India have developed biological methods for pretanning as well as better chromium management.

The higher cost associated to the treatment of effluents that to untreated effluent discharging leads to illegal dumping to save on costs. For instance, in Croatia in 2001, proper pollution abatement cost 70-100 USD/t of raw hides processed against 43 USD/t for irresponsible behavior.^[11]

No general study seems to exist but the current news is rife with documented examples.^{[clarification needed]} In November 2009 for instance, it was discovered that one of Uganda's main leather producing companies directly dumped its waste water in a wetland adjacent to Lake Victoria.^[12]

Role of enzymes[link]

Enzymes like proteases, lipases, and amylases have an important role in the soaking, dehairing, degreasing, and bating operations of leather manufacturing.

Proteases are the most commonly used enzymes in leather production. The enzyme used should not damage or dissolve collagen or keratin, but should be able to hydrolyze casein, elastin, albumin, and globulin-like proteins, as well as non-structured proteins which are not essential for leather making. This process is called bating.^[13]

Lipases are used in the degreasing operation to hydrolyze fat particles embedded in the skin.^[14]

Amylases are used to soften skin, to bring out the grain, and to impart strength and flexibility to the skin. These enzymes are rarely used.

Preservation and conditioning[link]

The natural fibers of leather will break down with the passage of time. Acidic leathers are particularly vulnerable to red rot, which causes powdering of the surface and a change in consistency. Damage from red rot is aggravated by high temperatures and relative humidities and is irreversible.

Exposure to long periods of low relative humidities (below 40%) can cause leather to become desiccated, irreversibly changing the fibrous structure of the leather.

Various treatments are available such as conditioners, but these are not recommended by conservators since they impregnate the structure of the leather artifact with active chemicals, are sticky, and attract stains.^{[citation needed]} Saddle soap is used for cleaning, conditioning and softening leather. Leather shoes are widely conditioned with shoe polish.

Book binding[link]

Leather used in book binding has many of the same preservation needs: protection from high temperatures, high relative humidity, low relative humidity, fluctuations in relative humidity, light exposure, dust buildup, pollution, mold, and bug infestation.^[15][16]

For books with red rot, acid-free phase boxes and/or polyester dust jackets (Dupont Mylar Type D or ICI Mellinex 516) are recommended to protect the leather from further handling damage and as well as to prevent the residues from getting on hands, clothes, the text block, and nearby books.^[17]

The debate on the use of dressings for preservation of book bindings has spanned several decades as research and experimental evidence have slowly accumulated. The main argument is that, done incorrectly, there are multiple disadvantages and that, done correctly, there is little to no preservation advantage. Pamphlets and guidelines give numerous downsides to dressings use, including: the dressing becoming increasingly acidic and will discolor and stain the leather, oxidize (penetration and expansion of oils including displacement and weakening of fibers) and stiffen, leave a sticky surface, collect dust, wick into adjacent materials, form unstable surface spews, encourage biological deterioration and mold growth, block surface porosity, impede further treatment, wet and swell the leather, affect surface finishes, and desiccate or dry out the leather.^[18] Meanwhile, scientific experiments have shown no substantial benefits.^[19] The main authorities on the subject therefore discourage it, with a caveat for special cases done under the direction of a conservator.^[15][17][18]

Leathercrafting[link]

Leather can be decorated by a variety of methods, including pyrography and beading.

Cordwain, "Cordovan" or "Spanish leather"[link]

Fragment of Cordwain

Cordwain, once a synonym of cordovan (through Old French cordewan) meaning "from Córdoba" describes painted or gilded embossed leather hangings manufactured in panels and assembled for covering walls as an alternative to tapestry. Such "Cordovan leathers" were a north African style that was introduced to Spain in the ninth century (hence it is sometimes referred to as 'Spanish leather'); in Spain such embossed leather hangings were known as guadamecí or guadamecil, from the Libyan town of Ghadames, while cordobanes signified soft goat leather.^[20] Leather was even more protection against draughts and dampness than tapestry and unaffected by insects. From the fourteenth century, the technique in which panels of wet leather were shaped over wooden moulds, painted, then oil-gilded and lacquered, reached Flanders and Brabant in the Low Countries. Though there were craftsmen in several cities (such as Antwerp, Brussels, and Ghent), the major handicraft center for this cordwain was Mechelen, where it was mentioned as early as 1504.

Embossed gilded leather hangings in a Dutch interior, ca 1730, painted by Philip van Dijk (Mauritshuis)

Patterns for these panels followed fashions in silk damask, at some lag in time, since the high-relief wooden moulds were laborious to make. After the second half of the 18th century, this luxurious artisan product was no longer made,^[21] its place taken in part by chintz hangings and printed wallpapers. Cordwainer is still used to describe someone in the profession of shoemaking.

In modern culture[link]

A motorcycle-style leather jacket.

Due to its excellent resistance to abrasion and wind, leather found a use in rugged occupations. The enduring image of a cowboy in leather chaps gave way to the leather-jacketed and leather-helmeted aviator. When motorcycles were invented, some riders took to wearing heavy leather jackets to protect from road rash and wind blast; some also wear chaps or full leather pants to protect the lower body. Top-quality motorcycle leather is superior to any practical man-made fabric for abrasion protection and is still used in racing. Many sports still use leather to help in playing the game or protecting players; its flexibility allows it to be formed and flexed.

The term leathering is sometimes used in the sense of a physical punishment (such as a severe spanking) applied with a leather whip, martinet, etc.

Leather fetishism is the name popularly used to describe a fetishistic attraction to people wearing leather, or in certain cases, to the garments themselves.

Many rock groups (particularly heavy metal and punk groups in the 1980s) are well known for wearing leather clothing. Leather clothing, particularly jackets, are common in the heavy metal and Punk subculture. Extreme metal bands (especially black metal bands) and Goth rock groups have extensive leather clothing, i.e. leather pants, accessories, etc.

Many cars and trucks come with optional or standard "leather" seating. This can range from cheap vinyl imitation leather, found on some low cost vehicles, to real Napa leather, found on certain models of luxury car brands like Mercedes-Benz, BMW, and Audi.

Leather is used exclusively by publishers like The Easton Press to bind books, for both practical and aesthetic purposes.

Religious sensitivities[link]

In religiously diverse countries, leather vendors are typically careful to clarify the kinds of leather used in their products. For example, leather shoes will bear a label identifying the animal from which the leather was taken. In this way, a Muslim would not accidentally purchase pigskin leather,^{[citation needed]} and a Hindu could avoid cow leather. Many Hindus who are vegetarians will not use any kind of leather.

Such taboos increase the demand for religiously neutral leathers like ostrich and deer.

Judaism forbids the comfort of wearing shoes made with leather on Yom Kippur, Tisha B'Av, and during mourning.^[22]

Jainism prohibits the use of leather since it is obtained by killing animals.

Vegans are against using products made from animals and would not wear, or use, leather.

Alternatives[link]

Some Vegans and animal rights activists boycott the use of all items made from leather, believing the practice of wearing animal hides to be unnecessary and cruel in today's society. Animal rights groups such as PETA have called for boycotts and encourage the use of alternative materials such as synthetic leathers.

Many pseudo-leather materials have been developed, allowing those who wish to wear leather-like garments to do so without actually wearing leather. One example of this is vegan microfiber, which claims to be stronger than leather when manufactured with strength in mind. Vinyl materials, pleather, Naugahyde, Durabuck, NuSuede, Hydrolite, and other alternatives exist, providing some features similar to leather.^{[citation needed]}

However, environmental and safety issues exist with the choice of vegans. Microfiber textiles tend to be flammable and emit toxic gases when burning.^{[citation needed]} They are made with synthetic fibers such as polyester and nylon which are made from petrochemicals. Microfibers are not made from a renewable resource and are not biodegradable.

Tori Amos (born Myra Ellen Amos; August 22, 1963) is an American pianist, singer-songwriter and composer. Amos originally served as the lead singer of 1980s synthpop group Y Kant Tori Read, and as a solo artist was at the forefront of a number of female singer-songwriters in the early 1990s. She was also noteworthy early in her solo career as one of the few alternative rock performers to use a piano as her primary instrument. Some of her charting singles include "Crucify", "Silent All These Years", "God", "Cornflake Girl", "Caught a Lite Sneeze", "Professional Widow", "Spark", "1000 Oceans", and "A Sorta Fairytale", her most commercially successful single in the U.S. to date.^[2]

As of 2005, Amos had sold 12 million albums worldwide.^[3] She has been nominated for 8 Grammy Awards. Amos was also named one of People Magazine's 50 Most Beautiful People in 1996.^[4]

Early life[link]

Amos was born in Newton, North Carolina. When she was two, her family moved to Baltimore, Maryland, where she began to play the piano. By age five, she had begun composing instrumental pieces on piano and, while living in Rockville, Maryland, she won a full scholarship to the Preparatory Division of the Peabody Conservatory of Music.^[5] Her scholarship was discontinued at age 11 and she was asked to leave. Amos has asserted that she lost the scholarship because of her interest in rock and popular music, coupled with her dislike for reading from sheet music.^[5] In 1972, The Amos family moved to Silver Spring, Maryland, where her father, Reverend Edison Amos, became pastor of the Good Shepherd United Methodist church. At the age of 13 she began playing at gay bars and piano bars, chaperoned by her father.^[5][6]

Amos first came to local notice by winning a county teen talent contest in 1977, singing a song called "More Than Just a Friend". As a senior at Richard Montgomery High School, she co-wrote "Baltimore" with her brother Mike Amos for a competition involving the Baltimore Orioles. The song won the contest and became her first single, released as a 7" single pressed locally for family and friends during 1980 with another Amos-penned composition as a B-side, "Walking With You". Prior to this period she performed under her middle name, Ellen, but permanently adopted Tori after a friend's boyfriend told her it suited her.^[7] At age 21, Amos moved to Los Angeles to pursue her music career after several years performing on the piano bar circuit of the D.C. area.^[8]

Atlantic years (1986–2001)[link]

Y Kant Tori Read[link]

In 1986, Amos formed a music group, Y Kant Tori Read, the name of which was a reference to her days at the Peabody Conservatory, where she was able to play songs on her piano by ear, but was never successful at sight reading.^[9] In addition to Amos, the group was composed of Steve Caton (who would later play guitars on all her subsequent albums until 1999), drummer Matt Sorum, bass player Brad Cobb and, for a short time, keyboardist Jim Tauber. Following several phases of writing and recording, during which Amos has since asserted that the band lost their musical edge and direction due to interference from record executives, in July 1988, the Y Kant Tori Read's self-titled debut album was released. Although its producer, Joe Chiccarelli, has stated that Amos was very happy with the album at the time,^[10] it is now out of print and Amos has expressed no interest in reissuing it.^[11] Following the album's commercial failure and the group's subsequent disbanding, Amos began working with other artists (including Stan Ridgway, Sandra Bernhard, and Al Stewart) as a backup vocalist. She also recorded a song called "Distant Storm" for the film China O'Brien; in the credits, the song is attributed to a band called Tess Makes Good.^[12] It was the only song recorded by the band, and its only commercial release was in the film.

Solo career[link]

Despite the disappointing reaction to Y Kant Tori Read, Amos still had to comply with her six-record contract with Atlantic Records, who in 1989 wanted a new record by March 1990. The initial recordings were declined by the label, which Amos felt was because the album had not been properly presented.^[13] The album was reworked and expanded under the guidance of Doug Morris and the musical talents of Steve Caton, Eric Rosse, Will MacGregor, Carlo Nuccio, and Dan Nebenzal, resulting in Little Earthquakes, an album recounting her religious upbringing, sexual awakening, struggle to establish her identity, and sexual assault. This album became her commercial and artistic breakthrough.

Amos traveled to New Mexico with personal and professional partner Eric Rosse in 1993 to write and largely record her second solo record, Under the Pink. The album was received with mostly favorable reviews and sold enough copies to chart at #12 on the Billboard 200, a significantly higher position than the preceding album's position at #54 on the same chart.^[14]

Her third solo album, Boys for Pele, was released in January 1996. The album was recorded in an Irish church, in Delgany, County Wicklow, with Amos taking advantage of the church recording setting to create an album ripe with baroque influences, lending it a darker sound and style. She added harpsichord, harmonium, and clavichord to her keyboard repertoire, and also included such anomalies as a gospel choir, bagpipes, church bells, and drum programming. The album garnered mixed reviews upon its release, with some critics praising its intensity and uniqueness while others bemoaned its comparative impenetrability. Despite the album's erratic lyrical content and instrumentation, the latter of which kept it away from mainstream audiences, Boys for Pele is Amos's most successful simultaneous transatlantic release, reaching #2 on both the Billboard 200 and the UK Top 40 upon its release at the height of her fame.^[15][16]

Fueled by the desire to have her own recording studio to distance herself from record company executives,^[17] Amos had the barn of her home in Cornwall converted into a state-of-the-art recording studio, Martian Engineering Studios.

From the Choirgirl Hotel and To Venus and Back, released in May 1998 and September 1999, respectively, differ greatly from previous albums as Amos's trademark acoustic piano-based sound is largely replaced with arrangements that include elements of electronica, dance music, vocal washes and sonic landscapes. The underlying themes of both albums deal with womanhood, and Amos's own miscarriages and marriage. Reviews for From the Choirgirl Hotel were mostly favorable and praised Amos's continued artistic originality. While not her highest chart debut, debut sales for From the Choirgirl Hotel are Amos's best to date, selling 153,000 copies in its first week.^[18] To Venus and Back, a two-disc release of original studio material and live material recorded from the previous world tour, received mostly positive reviews and included the first major-label single available for sale as a digital download.^[19]

Motherhood inspired Amos to produce a cover album, recording songs written by men about women and reversing the gender roles to show a woman's perspective.^[20] That idea grew into Strange Little Girls, released in September 2001, one year after giving birth to her daughter. The album is Amos's first concept album, with artwork featuring Amos photographed in character of the women portrayed in each song. Amos would later reveal that a stimulus for the album was to end her contract with Atlantic without giving them new original songs; Amos felt that since 1998, the label had not been properly promoting her and had trapped her in a contract by refusing to sell her to another label.^[21]

Epic Records years (2002–07)[link]

With her Atlantic contract fulfilled after a 15-year stint, Amos signed to Epic in late 2001. In October 2002, Amos released Scarlet's Walk, another concept album. Described as a "sonic novel", the album explores Amos's alter ego, Scarlet, intertwined with her cross-country concert tour following 9/11. Through the songs, Amos explores such topics as the history of America, American people, Native American history, pornography, masochism, homophobia and misogyny. The album had a strong debut,^[22][23] demonstrating that Amos' fan base remained intact through the label change. However, Scarlet's Walk is Amos' last album to date to reach certified gold status.^[24]

Amos in concert in June, 2005

Not long after Amos was ensconced with her new label, she received unsettling news when Polly Anthony resigned as president of Epic Records in 2003. Anthony had been one of the primary reasons Amos signed with the label and as a result of her resignation, Amos formed the Bridge Entertainment Group. Further trouble for Amos occurred the following year when her label, Epic/Sony Music Entertainment, merged with BMG Entertainment as a result of the industry's decline.^[25] Amos would later hint in interviews that during the creation of her next album, those in charge at the label following the aforementioned merger were interested "only in making money", the effects of which on the album have not been disclosed.^{[citation needed]}

Amos released two more albums with the label, The Beekeeper (2005) and American Doll Posse (2007). Both albums received mixed reviews, some of which stated that the albums suffered from being too long.^[26][27] The Beekeeper was conceptually influenced by the ancient art of beekeeping, which she considered a source of female inspiration and empowerment. Through extensive study, Amos also wove in the stories of the Gnostic gospels and the removal of women from a position of power within the Christian church to create an album based largely on religion and politics. The album debuted at #5 on the Billboard 200,^[28] placing her in an elite group of women who have secured five or more US Top 10 album debuts.^[29] American Doll Posse, another concept album, was fashioned around a group of girls (the "posse") who are used as a theme of alter-egos of Amos's. Musically and stylistically, the album saw Amos return to a more confrontational nature.^[30] Like its predecessor, American Doll Posse debuted at #5 on the Billboard 200.^[14]

During her tenure with Epic Records, Amos also released a retrospective collection titled Tales of a Librarian (2003) through her former label, Atlantic Records; a two-disc DVD set Fade to Red (2006) containing most of Amos's solo music videos, released through the Warner Bros. reissue imprint Rhino; a five disc box set titled A Piano: The Collection (2006), celebrating Amos's 15 year solo career through remastered album tracks, remixes, alternate mixes, demos, and a string of unreleased songs from album recording sessions, also released through Rhino; and numerous official bootlegs from two world tours, The Original Bootlegs (2005) and Legs & Boots (2007) through Epic Records.

Universal Music years (2008–present)[link]

Universal Republic (2008–2011)[link]

In May 2008, Amos announced that, due to creative and financial disagreements with Epic Records, she had negotiated an end to her contract with the record label, and would be operating independently of major record labels on future work.^[31][32] In September of the same year, Amos released a live album and DVD, Live at Montreux 1991/1992, through Eagle Rock Entertainment, of two performances she gave at the Montreux Jazz Festival very early on in her career while promoting her debut solo album, Little Earthquakes. By December, after a chance encounter with chairman and CEO of Universal Music Group, Doug Morris, Amos signed a "joint venture" deal with Universal Republic Records.^{[33][34][35][36]}

Abnormally Attracted to Sin, Amos's tenth solo studio-album and her first album released through Universal Republic, was released in May 2009 to mostly positive reviews. The album debuted in the top 10 of the Billboard 200,^[37] making it the Amos' seventh album to do so.^[38] Abnormally Attracted to Sin, admitted Amos, was a "personal album", not a conceptual one.^[39] Continuing her distribution deal with Universal Republic, Amos released Midwinter Graces, her first seasonal album, in November of the same year. The album features reworked versions of traditional carols, as well as original songs written by Amos.^[40]

During her contract with the label, Amos recorded vocals for two songs for David Byrne's collaboration album with Fatboy Slim, entitled Here Lies Love,^[41] which was released in April 2010. In July of the same year, the DVD Tori Amos- Live from the Artists Den was released exclusively through Barnes & Noble.

After a brief tour from June to September 2010, Amos released the highly exclusive live album From Russia With Love in December the same year, recorded live in Moscow on 3 September 2010. The limited edition set included a signature edition Lomography Diana F+ camera, along with 2 lenses, a roll of film and 1 of 5 photographs taken of Tori during her time in Moscow. The set was released exclusively through toriamos.com and only 2000 were produced. It is currently unknown as to whether the album will receive a mass release.

Deutsche Grammophon (2011–present)[link]

In September 2011, Amos released her first classical music album, Night of Hunters, featuring variations on a theme to pay tribute to such renowned composers as Bach, Chopin, Debussy, Granados, Satie and Schubert, through the Deutsche Grammophon label, a division of Universal Music Group. She is currently writing the music for Samuel Adamson's musical adaptation of the George MacDonald story The Light Princess for the Royal National Theatre, which was originally expected to debut in spring 2012^[42] but has now been deferred.^[43] Amos has, however, confirmed the release of an album in 2012 marking the 20th anniversary of her debut album Little Earthquakes.^[44] The album will consist of songs from her back catalogue rearranged and performed by the Metropole Orchestra.

On May 1st, 2012, Amos announced the formation of her own record label Transmission Galactic, which she intends to use to develop new artists.

In print[link]

Released in conjunction with The Beekeeper, Amos co-authored an autobiography with rock music journalist Ann Powers entitled Piece by Piece (2005). The book's subject is Amos's interest in mythology and religion, exploring her songwriting process, rise to fame, and her relationship with Atlantic Records.

Image Comics released Comic Book Tattoo (2008), a collection of comic stories, each based on or inspired by songs recorded by Amos. Editor Rantz Hoseley worked with Amos to gather 80 different artists for the book, including Pia Guerra, David Mack, and Leah Moore.

Additionally, Amos and her music have been the subject of numerous official and unofficial books, as well as academic critique, including Tori Amos: Lyrics (2001) and an earlier biography, Tori Amos: All These Years (1996).^[45][46][47]

"Tori Amos: In the Studio" (2011) by Jake Brown features an in-depth look at Amos's career, discography and recording process.^[48]

In 2011 Adrienne Trier-Bieniek, a sociology graduate student at Western Michigan University, received her PhD for a dissertation entitled “All I Am: Defining Music as an Emotional Catalyst through a Sociological Study of Emotions, Gender and Culture". Trier-Bieniek focused on Amos' female fans and the emotional support they receive from listening to Amos' music. Along with Patricia Leavy, Trier-Bieniek contributed a chapter to the book "The Art of Social Critique"^[49] which addressed Amos' later albums and songwriting skills.

Personal life[link]

Family[link]

Amos in 1993 Alexandra Palace, London

Amos is the third child of Rev. Dr. Edison and Mary Ellen Amos. She was born at the Old Catawba Hospital in Newton, North Carolina, during a trip from their Georgetown home in Washington, D.C. Her maternal grandparents were of mixed European and Eastern Cherokee ancestry; of particular importance to her as a child was her grandfather, Calvin Clinton Copeland, who was a great source of inspiration and guidance to her as a young child, offering a more pantheistic spiritual alternative to her father and paternal grandmother's traditional Christianity.^[50]

Early in her professional career, Amos befriended author Neil Gaiman, who became a fan after she referenced him in the song "Tear in Your Hand" and also in print interviews.^[51] Although created before the two met, the character Delirium from Gaiman's The Sandman series (or even her sister Death) is inspired by Amos; Gaiman has stated that they "steal shamelessly from each other".^[52] She wrote the foreword to his collection Death: The High Cost of Living; he in turn wrote the introduction to Comic Book Tattoo. Gaiman is godfather to her daughter and a poem written for her birth, Blueberry Girl, was published as a children's book of the same name in 2009.^[53]

Amos married English sound engineer Mark Hawley on February 22, 1998. Their only child, a daughter named Natashya "Tash" Lórien Hawley, was born on September 5, 2000, a few weeks after Tori's 37th birthday. The family divides their time between Sewall's Point in Florida, Kinsale^[54] (County Cork) in Ireland, and Cornwall in England.

Activism[link]

In June 1994, Amos co-founded RAINN, The Rape, Abuse and Incest National Network, a toll-free help line in the US connecting callers with their local rape crisis center. Amos, herself a survivor of sexual assault,^[55] was seen as unlocking the silence of her assault through her music; thus "Unlock the Silence" went on to become a year-long campaign for RAINN when Amos became a national spokesperson for the organization. By the summer of 2006, RAINN had received its one millionth caller^[56] and the organization's success has led to it ranking in "America's 100 Best Charities" by Worth, and one of the "Top 10 Best Charities" by Marie Claire.

Tours[link]

Amos, who has been performing in bars and clubs from as early as 1976 and under her professional name as early as 1991 has performed more than 1,000 shows since her first world tour in 1992. In 2003, Amos was voted fifth best touring act by the readers of Rolling Stone magazine. Her concerts are notable for their changing set lists from night to night.

Little Earthquakes Tour 

Amos's first world tour began on January 29, 1992 in London and ended on November 30, 1992 in Auckland. She performed solo with a Yamaha CP-70 unless the venue was able to provide a piano.^[57][58] The tour included 142 concerts around the globe.

Under the Pink Tour 

Amos's second world tour began on February 24, 1994 in Newcastle upon Tyne and ended on December 13, 1994 in Perth, Western Australia. Amos performed solo each night on her iconic Bösendorfer^{[citation needed]} piano, and on a prepared piano during "Bells for Her". The tour included 181 concerts.

Dew Drop Inn Tour 

The third world tour began on February 23, 1996 in Ipswich, England, and ended on November 11, 1996 in Boulder. Amos performed each night on piano, harpsichord, and harmonium, with Steve Caton on guitar on some songs. The tour included 187 concerts.

Plugged '98 Tour 

Amos's first band tour. Amos, on piano and Kurzweil keyboard, was joined by Steve Caton on guitar, Matt Chamberlain on drums, and Jon Evans on bass. The tour began on April 18, 1998 in Fort Lauderdale and ended on December 3, 1998 in East Lansing, Michigan, including 137 concerts.

Five and a Half Weeks Tour / To Dallas and Back 

Amos's fifth tour was North America–only. The first part of the tour was co-headlining with Alanis Morissette and featured the same band and equipment line-up as in 1998. Amos and the band continued for eight shows before Amos embarked on a series of solo shows. The tour began on August 18, 1999 in Fort Lauderdale, Florida and ended on December 9, 1999 in Denver, including 46 concerts.

Strange Little Tour 

This tour was Amos's first since becoming a mother in 2000 and her first tour fully solo since 1994 (Steve Caton was present on some songs in 1996). It saw Amos perform on piano, Rhodes piano, and Wurlitzer electric piano, and though the tour was in support of her covers album, the set lists were not strictly covers-oriented. Having brought her one-year-old daughter on the road with her, this tour was also one of Amos's shortest ventures, lasting just three months. It began on August 30, 2001 in London and ended on December 17, 2001 in Milan, including 55 concerts.

On Scarlet's Walk / Lottapianos Tour 

Amos's seventh tour saw her reunited with Matt Chamberlain and Jon Evans, but not Steve Caton. The first part of the tour, which featured Amos on piano, Rhodes, and Wurlitzer, was six months long and Amos went out again in the summer of 2003 for a tour with Ben Folds opening. The tour began on November 7, 2002 in Tampa and ended on September 4, 2003 in West Palm Beach, featuring 124 concerts. The final show of the tour was filmed and released as part of a DVD/CD set titled Welcome to Sunny Florida (the set also included a studio EP titled Scarlet's Hidden Treasures, an extension of the Scarlet's Walk album).

Original Sinsuality Tour / Summer of Sin 

This tour began on April 1, 2005 in Clearwater, Florida, with Amos on piano, two Hammond B-3 organs, and Rhodes. The tour also encompassed Australia for the first time since 1994. Amos announced at a concert on this tour that she would never stop touring but would scale down the tours. Amos returned to the road in August and September for the Summer of Sin North America leg, ending on September 17, 2005 in Los Angeles. The tour featured "Tori's Piano Bar", where fans could nominate cover songs on Amos's website which she would then choose from to play in a special section of each show. One of the songs chosen was the Kylie Minogue hit "Can't Get You Out of My Head", which Amos dedicated to her the day after Minogue's breast cancer was announced to the public. Other songs performed by Amos include The Doors' "People are Strange", Depeche Mode's "Personal Jesus", Joni Mitchell's "The Circle Game", Madonna's "Live to Tell" and "Like a Prayer", Björk's "Hyperballad", Led Zeppelin's "When the Levee Breaks" (which she debuted in Austin, Texas, just after the events of Hurricane Katrina), Kate Bush's "And Dream of Sheep" and Crowded House's "Don't Dream It's Over", dedicating it to drummer Paul Hester who had died a week before. The entire concert tour featured 82 concerts, and six full-length concerts were released as The Original Bootlegs.

American Doll Posse World Tour 

This was Amos's first tour with a full band since her 1999 Five and a Half Weeks Tour, accompanied by long-time band mates Jon Evans and Matt Chamberlain, with guitarist Dan Phelps rounding out Amos's new band.^[59] Amos's equipment included her piano, a Hammond B-3 organ, and two Yamaha S90 ES keyboards. The tour kicked off with its European leg in Rome, Italy on May 28, 2007, which lasted through July, concluding in Israel; the Australian leg took place during September; the North American leg lasted from October to December 16, 2007, when the tour concluded in Los Angeles. Amos opened each show dressed as one of the four non-Tori personae from the album, then Amos would emerge as herself to perform for the remaining two-thirds of the show. The entire concert tour featured 93 concerts, and 27 full-length concerts of the North American tour were released as official bootlegs in the Legs and Boots series.

Sinful Attraction Tour 

For her tenth tour, Amos returned to the trio format of her 2002 and 2003 tours with bassist Jon Evans and drummer Matt Chamberlain while expanding her lineup of keyboards by adding three M-Audio MIDI controllers to her ensemble of her piano, a Hammond B-3 organ, and a Yamaha S90 ES keyboard. The North American and European band tour began on 10 July 2009 in Seattle, Washington and ended in Warsaw on 10 October 2009. A solo leg through Australia began in Melbourne on 12 November 2009 and ended in Brisbane on 24 November 2009. The entire tour featured 63 concerts.

Night of Hunters tour
