25 (twenty-five) is the natural number following 24 and preceding 26.

In mathematics[link]

It is a square number, being 5² = 5 × 5. It is the smallest square that is also a sum of two (non-zero) squares: 25 = 3² + 4². Hence it often appears in illustrations of the Pythagorean theorem.

25 is a centered octagonal number, a centered square number, and an automorphic number.

25 percent is equal to 1/4.

25 has an aliquot sum of 6 and number 6 is the first (or smallest) number to have an aliquot sequence that does not culminate in 0 through a prime. Twenty-five is the aliquot sum of three integers; 95, 119, and 143. Twenty-five is the second composite member of the 6-aliquot tree.

It is the smallest base 10 Friedman number as it can be expressed by its own numbers: 5².

It is also a Cullen number. 25 is the smallest pseudoprime satisfying the congruence 7ⁿ = 7 mod n.

25 is the smallest aspiring number — a composite non-sociable number whose aliquot sequence does not terminate.

According to the Shapiro inequality, 25 is the least odd integer n such that there exist Failed to parse (Missing texvc executable; please see math/README to configure.): x_1, x_2, \dots, x_n

such that 

Failed to parse (Missing texvc executable; please see math/README to configure.): \sum_{i=1}^{n} \frac{x_i}{x_{i+1}+x_{i+2}} < \frac{n}{2}

where Failed to parse (Missing texvc executable; please see math/README to configure.): x_{n+1}=x_1, x_{n+2}=x_2 .

Within base 10 one can readily test for divisibility by 25 by seeing if the last two digits of the number match 25, 50, 75 or 00.

25 and 49 are the only perfect squares in the following list:

13,25,37,49,511,613,715,817,919,1021,1123,1225,1327,1429...etc.

The formula in this list can be described as Failed to parse (Missing texvc executable; please see math/README to configure.): 10^n * Z + (2Z + 1)

where n clearly depends on the number of digits in Z and in 2Z+1.

In base 30, 25 is a 1-automorphic number (displayed as the numeral 'P' or 'R' dependant on the chosen digit set), and in base 10 a 2-automorphic number.

Christopher Edward Martin (born March 21, 1966),^[1] better known by his stage name DJ Premier (also known as Preem, Premo, or Primo for short), is an American record producer and DJ, and was the instrumental half of the hip hop duo Gang Starr, together with emcee Guru. Born in Houston and raised in Prairie View, Texas, he has lived in Brooklyn, New York, for much of his professional career. Rolling Stone identified Premier as arguably Hip-Hop's greatest producer of all time.^[2]

The Source named DJ Premier one of the five greatest producers in hip-hop history,^[3] while the editors of About.com ranked him #1 on their Top 50 Hip-Hop Producers list.^[4] He also made the "Finals" in the search for The Greatest Hip-Hop Producer of All Time by Vibe.^[5] He attended Prairie View A&M University.^[6]

Productions[link]

Premier is known for producing all of Gang Starr's songs as well as many of the Gang Starr Foundation's songs. His work also includes production for heavyweight rappers such as (alphabetic order) Apathy, Big L, Bun B, Canibus, D.I.T.C., Fat Joe, Game, Jay-Z, Kanye West, KRS-One, Lord Finesse, M.O.P., Mos Def, Nas, Rakim, Royce Da 5'9", The LOX, The Notorious B.I.G., Snoop Dogg, Xzibit, rock band Limp Bizkit, Big L, Big Daddy Kane, Ill Bill, Joell Ortiz, and pop/R&B singer Christina Aguilera, among many others.

Premier collaborated with MC Jeru the Damaja on the album The Sun Rises in the East, released in 1994, as well as the 1996 follow-up, Wrath of the Math.^[1] Also from the Gang Starr Foundation, Premier produced and supervised Group Home's Livin' Proof; although overlooked at the time of its 1995 release, the album has since come to find similar acclaim.^[1] Among others in that are closely tied to the Gang Starr Foundation who have worked with DJ Premier include Afu Ra, Bahamadia, Krumbsnatcha, Big Shug, Smiley the Ghetto Child, and NYGz. He recently produced the majority of Blaq Poet's Tha Blaqprint in 2009 and will produce the entirety of NYGz debut album.

Style and influences[link]

DJ Premier's style of production epitomizes the New York sound of his earlier peers. He is known for sampling jazz, funk, and soul artists, as well as sampling an artist's past work when creating a new track for that same artist. For example, on Jay-Z's "So Ghetto", from the 1999 album, Vol. 3… Life and Times of S. Carter, Premier samples an older Jay-Z song, 1997's "Who You Wit II".^[7] In addition, his encyclopedic memory of hip-hop lyrics allows him to distinctively speak with his hands by scratching in lyrics from several different songs to construct new phrases.^[8] Premier's beats are known for his oft-imitated combinations of short vocal samples, often from multiple artists, to create a chorus. Premier has also experimented with atonal samples that are not confined to soul, jazz, and funk. For example, he sampled chopped up seminal electro-acoustic music from the 1960s on the track “Mental Stamina” by Jeru the Damaja.

In an interview with XXL Magazine, DJ Premier was asked how his sound evolved, to which he replied, "Marley Marl is my number one inspiration. Jam Master Jay, Mixmaster Ice and UTFO. Grandmaster D and Whodini. DJ Cheese, Grandmaster Flash, Kool Herc, Afrika Bambaataa. Jazzy Jay, even Cut Creator. Seeing them do what they do. It’s black music, it’s black culture, it comes from the ghetto. How can you not relate to ghetto people when that’s the rawest form of blackness? Even though it’s not a good place in regards to the economy and how bad people have it in the neighborhood, the realism’s there, and that’s what we were born out of. So I very much pay respect by doing the same type of music in return." DJ Premier attended Prairie View A & M University and may have been influenced by the musical atmosphere at the university.^[9]

Relationships with artists[link]

The early line-up of the Gang Starr Foundation in the mid-1990s included Jeru The Damaja, Group Home, Big Shug, and Gang Starr. DJ Premier was fully responsible for the production of Jeru the Damaja's first two albums, The Sun Rises in the East and Wrath of the Math. Jeru released three albums since then, with Premier having nothing to do with any of them.^[1]

As far as Group Home was concerned, Premier commented, "They don't respect what fed them," in a 2003 interview, going on to say that the only reason he produced a track on their second album was because Guru said he would rhyme on it.^[10]

Besides the Gang Starr Foundation, Premier is closely affiliated with M.O.P., which he names as one of his all-time favorite groups. The relationship started with the remix of “Rugged, Neva Smoove” in 1994, a single from the group's first album, which also included the exclusive B-side “Downtown Swinga.” From then, Premier produced about one-third of the songs on each subsequent album and overseeing and mixing the projects. On M.O.P.'s 2009 Foundation album, however, DJ Premier provided only one track, which was called "What I Wanna B."

Recent and future projects[link]

DJ Premier has his own record company named Year Round Records. Among its artists are New York group NYGz, New Jersey rapper Nick Javas, and Houston rapper Khaleel. Tha Blaqprint by Blaq Poet, which has thirteen Premier productions, was released by Year Round Records through Fat Beats Records. On December 7, Premier's label Year Round Records released a digital compilation album titled Get Used to Us. At the moment Year Round plans to release a debut album fully produced by DJ Premier with the NYGz tenatively called Hustla's Union: Local NYG along with a Nick Javas debut album named Destination Unknown. Khaleel, another label-mate of Year Round Records, is planned to release a debut album titled Already!.

DJ Premier hosts a weekly 2 hour show Live From HeadQCourterz on SIRIUS Satellite Radio's Hip-Hop Nation on Fridays.

DJ Premier was one of the artists followed in the 2012 documentary Re:GENERATION music project. The film followed his production of the song Regeneration using live performance of his work by the Berklee Symphony Orchestra [1]

In a recent interview, DJ Premier said he will produce a beat for Immortal Technique's upcoming album, titled The Middle Passage. He contributed a song on Game's last album The R.E.D. Album called "Born in the Trap." and a song on Bushido's last album Jenseits von Gut und Böse.^[6] In an interview in 2012, DJ Premier confirmed on Shade45 that he is working with Eminem on his upcoming album.

He was a founder of the band Squeeze (1974-1980 & 1985-1990) and his work has involved him with many artists including Sting, Eric Clapton, George Harrison, David Gilmour, Magazine and Bono.

Holland is a published author and appears on television shows besides his own and contributes to radio shows. In 2004, he collaborated with Tom Jones on an album of traditional R&B music. He currently hosts Later... with Jools Holland, a music-based show aired on BBC2, on which his annual show Hootenanny, is based.^[1]

Life and career[link]

His great grandfather came from Ireland.^[2]

Holland played as a session musician before finding fame, and his first studio session was with Wayne County & the Electric Chairs in 1976 on their track "F*ck Off."^[3]

Holland was a founding member of the British pop band Squeeze, formed in March 1974, in which he played keyboards until 1981 and helped the band to achieve millions of record sales, before pursuing his solo career.^[3]

Holland began issuing solo records in 1978, his first EP being Boogie Woogie '78. He continued his solo career through the early 1980s, releasing an album and several singles between 1981 and 1984. He branched out into TV, co-presenting the Newcastle-based TV music show The Tube with Paula Yates. Holland achieved notoriety by inadvertently using the phrase "groovy fuckers" in a live, early evening TV trailer for the show, causing it to be suspended for six weeks.^[4] He referred to this in his sitcom "The Groovy Fellers" with Rowland Rivron.

In 1983 Holland played an extended piano solo on The The's re-recording of "Uncertain Smile" for the album Soul Mining. In 1985, Squeeze (which had continued in Holland's absence through to 1982) unexpectedly regrouped including Jools Holland as their keyboard player. Holland remained in the band until 1990, at which point, he again departed Squeeze on amicable terms to resume his solo career as a musician and a TV host.

In 1987, Holland formed The Jools Holland Big Band which consisted of himself and Gilson Lavis from Squeeze. This gradually became his 18-piece Rhythm & Blues Orchestra.^[3]

Between 1988 and 1990 he performed and co-hosted along with David Sanborn during the two seasons of the music performance program Sunday Night on NBC late-night television.^[5] Since 1992 he has presented the music program Later... with Jools Holland, plus an annual New Year's Eve Hootenanny.

In 1996, Holland signed a recording contract with Warner Bros. Records,^[3] and his records are now marketed through Rhino Records.

Holland has a touring band, The Rhythm And Blues Orchestra, which often includes singers Sam Brown and Ruby Turner. In January 2005 Holland and his band performed with Eric Clapton as the headline act of the Tsunami Relief Cardiff.

Personal[link]

Holland lives in the Westcombe Park area of Blackheath in South East London, where he had his studio, Helicon Mountain, built to his design, inspired by Portmeirion, the setting for the 1960s TV series The Prisoner.^[6] Holland owns costumes and props from the series and occasionally appears wearing the trademark brown-with-white-pipe blazer featured in the series. In 1987, Holland demonstrated his love of the series and starred in a spoof documentary, The Laughing Prisoner, with Stephen Fry, Terence Alexander and Hugh Laurie.^[6] Much of it was shot on location in Portmeirion, with archive footage of Patrick McGoohan, and featuring musical numbers from Siouxsie and the Banshees, Magnum and XTC. Holland performed a number towards the end of the program. His younger brother, Christopher, also plays organ in the Rhythm & Blues Orchestra, as well as being a singer-songwriter.

Holland was an interviewer for The Beatles Anthology TV project, and appeared in the 1997 film Spiceworld as a musical director.

He received an OBE in 2003 in the Queen's Birthday Honours list, for services to the British music industry as a television presenter and musician. In September 2006 Holland was appointed a Deputy Lieutenant for Kent.^[7] He is also known for his charity work: in June 2006 he performed in Southend for HIV/AIDS charity Mildmay,^[8] and in early 2007 he performed at Wells and Rochester Cathedrals to raise money for maintaining cathedral buildings.^[9] He is also patron of the Drake Music Project^[10] and has raised many thousands of pounds for the charity.

Holland was appointed an Honorary Fellow of Canterbury Christ Church University at a ceremony held at Canterbury Cathedral on 30 January 2009.^[11]

On 29 August 2005 Holland married Christabel McEwen, his girlfriend of 15 years (between 1983 and 1995 she had been married to Edward Lambton, 7th Earl of Durham, before they divorced). The wedding, at St James's Church, Cooling near Rochester, was attended by many celebrities, including Ringo Starr, Robbie Coltrane, Stephen Fry, Lenny Henry, Noel Gallagher, Dawn French and Jennifer Saunders.^[12]

Holland is also a patron for The Milton Rooms, an Arts centre in Malton, North Yorkshire, along with Bill Nighy, Imelda Staunton and Kathy Burke.^[13]

Writing[link]

His 2007 biography, Barefaced Lies and Boogie Woogie Boasts was BBC Radio 4 "Book of the Week" in the week beginning 8 October 2007 and was read by Holland. He is the author or joint author of four other books.
