The East River is a tidal strait in New York City. It connects Upper New York Bay on its south end to Long Island Sound on its north end. It separates Long Island (including the boroughs of Queens and Brooklyn) from the island of Manhattan and the Bronx on the North American mainland. In reference to its connection to Long Island Sound, it was once also known as the Sound River.

The strait was formed approximately 11,000 years ago at the end of the Wisconsin glaciation. The distinct change in the shape of the strait between the lower and upper portions is evidence of this glacial activity. The upper portion (from Long Island Sound to Hell Gate), running largely perpendicular to the glacial motion, is wide, meandering, and has deep narrow bays on both banks, scoured out by the glacier's movement. The lower portion (from Hell Gate to New York Bay) runs north-south, parallel to the glacial motion. It is much narrower, with straight banks. The bays that exist (or existed before being filled in by human activity), are largely wide and shallow.

Horace Swaby (June 21, 1954 – May 18, 1999), known as Augustus Pablo, was a Jamaican roots reggae and dub record producer, melodica player and keyboardist, active from the 1970s onwards. He popularized the use of the melodica (an instrument at that time primarily used to teach children music in the Jamaican public schools) in reggae music. He was a committed Rastafarian.

He was born in St. Andrew, Jamaica, and learned to play the organ at the Kingston College School. It was at that point an unnamed girl lent him the melodica. Fascinated by the instrument, Pablo rarely put it down. He also met Herman Chin Loy, who after working at his cousin Leslie Kong's Beverley's record shop, had set up his own Aquarius store in Half Way Tree. Swaby recorded early tracks including "Higgi Higgi", "East of the River Nile", "Song of the East" and "The Red Sea" between 1971 and 1973 for Chin-Loy's Aquarius Records. Chin Loy had previously used the name Augustus Pablo generically for keyboard instrumentals recorded by Lloyd Charmers and Glen Adams, and Swaby took the name for this recording.

Grover Washington, Jr. (December 12, 1943 - December 17, 1999) was an American jazz-funk / soul-jazz saxophonist. Along with George Benson, John Klemmer, David Sanborn, Bob James, Chuck Mangione, Herb Alpert, and Spyro Gyra, he is considered by many to be one of the founders of the smooth jazz genre.^{[citation needed]} He wrote some of his material and later became an arranger and producer.

Throughout the 1970s and 1980s, Washington made some of the genre's most memorable hits, including "Mister Magic," "Reed Seed," "Black Frost," "Winelight," "Inner City Blues" and "The Best is Yet to Come". In addition, he performed very frequently with other artists, including Bill Withers on "Just the Two of Us" (still in regular rotation on radio today), Patti LaBelle on "The Best Is Yet to Come" and Phyllis Hyman on "A Sacred Kind of Love". He is also remembered for his take on the Dave Brubeck classic "Take Five", and for his 1996 version of "Soulful Strut".

Washington had a preference for black nickel-plated saxophones made by Julius Keilwerth. These included a SX90R alto and SX90R tenor. He also played Selmer Mark VI alto in the early years. His main soprano was a black nickel plated H.Couf Superba II (also built by Keilwerth for Herbert Couf) and a Keilwerth SX90 in the last years of his life.

Stanley Clarke (born June 30, 1951 in Philadelphia, Pennsylvania) is an American jazz musician and composer known for his innovative and influential work on double bass and electric bass as well as for his numerous film and television scores. He is best known for his work with the fusion band Return to Forever, and his role as a bandleader in several trios and ensembles.

Clarke was born in Philadelphia. He was introduced to the bass as a schoolboy when he arrived late on the day instruments were distributed to students and acoustic bass was one of the few remaining selections. He is a graduate of Roxborough High School in Philadelphia. Having graduated from the Philadelphia Musical Academy, (which was absorbed into the University of the Arts in 1985), he moved to New York City in 1971 and began working with famous bandleaders and musicians including Horace Silver, Art Blakey, Dexter Gordon, Gato Barbieri, Joe Henderson, Chick Corea, Pharoah Sanders, Gil Evans and Stan Getz. He was an avid supporter of Scientology in his earlier musical productions, and referred to L. Ron Hubbard on most of his LP sleeves. His current association with Scientology is not known.

Laurie Spiegel (born September 20, 1945 in Chicago) is an American composer. She has worked at Bell Laboratories, in computer graphics, and is known primarily for her electronic-music compositions and her algorithmic composition software Music Mouse. She also plays the guitar and lute.

Spiegel was seen by some as a pioneer of the New York new-music scene. She withdrew from this scene in the early 1980s, believing that its focus had shifted from artistic process to product. While she continues to support herself through software development, Spiegel aims to use technology in music as a means of furthering her art rather than as an end in itself. In her words, "I automate whatever can be automated to be freer to focus on those aspects of music that can't be automated. The challenge is to figure out which is which."

Spiegel's realization of Johannes Kepler's "Harmonices Mundi" was chosen for the opening track on the "Sounds of Earth" section of the golden record placed on board the Voyager spacecraft in 1977. Her piece called "Sediment" was used in the "cornucopia scene" of the 2012 movie The Hunger Games.
