"Christian Ernest Marclay (born January 11, 1955) is a visual artist and composer. He holds both American and Swiss nationality.

Marclay's work explores connections between sound, noise, photography, video, and film. A pioneer of using gramophone records and turntables as musical instruments to create sound collages, Marclay is, in the words of critic Thom Jurek, perhaps the "unwitting inventor of turntablism." His own use of turntables and records, beginning in the late 1970s, was developed independently of but roughly parallel to hip hop's use of the instrument.

Christian Marclay was born on January 11, 1955 in San Rafael, Marin County, California, to a Swiss father and an American mother and raised in Geneva, Switzerland. He studied at the Ecole SupŽrieure d'Art Visuel in Geneva (1975Ð1977), the Massachusetts College of Art in Boston (1977Ð1980, Bachelor of Fine Arts) in the Studio for Interrelated Media Program, and the Cooper Union in New York (1978). As a student he was notably interested in Joseph Beuys and the Fluxus movement of the 1960s and 1970s. Long based in Manhattan, Marclay has in recent years divided his time between New York and London.

Citing the influence of John Cage, Yoko Ono and Vito Acconci, Marclay has long explored the rituals around making and collecting music. Drawn to the energy of punk rock, he began creating songs, singing to music on pre-recorded backing tapes. Unable to recruit a drummer for his 1979 performances with guitarist Kurt Henry, Marclay used the regular rhythms of a skipping LP record as a percussion instrument. These duos with Henry might be the first time a musician used records and turntables as interactive, improvising musical instruments.

Marclay sometimes manipulates or damages records to produce continuous loops and skips, and has said he generally prefers inexpensive used records purchased at thrift shops, as opposed to other turntablists who often seek out specific recordings. In 1998 he claimed never to have paid more than US$1 for a record. Marclay has occasionally cut and re-joined different LP records; when played on a turntable, these re-assembled records will combine snippets of different music in quick succession along with clicks or pops from the seams Ð typical of noise music Ð and when the original LPs were made of differently-colored vinyl, the reassembled LPs can themselves be considered as works of art.

Some of Marclay's musical pieces are carefully recorded and edited plunderphonics-style; he is also active in free improvisation. He was filmed performing a duo with Erikm for the documentary Scratch. His scene didn't make the final cut, but is included among the DVD extras.

Marclay released Record Without a Cover on Recycled Records in 1985, "...designed to be sold without a jacket, not even a sleeve!" Accumulating dust and fingerprints would enhance the sound. A review in Spin at the time cited Marclay's "coolest theatrical gesture" in his live performances of phonoguitar: the artist strapped a record player onto himself and played, for example, a Jimi Hendrix album. In Five Cubes (1989), he melted vinyl records into cubes. In the 1980s and early '90s, he invented album covers. The Sound of Silence (1988) is a black-and-white photograph of the Simon & Garfunkel single of the same title. In a series of cyanotypes (2007Ð09), white negatives against a blue background, he unspooled cassette tapes.

Thom Jurek writes that "While many intellectuals have made wild pronouncements about Marclay and his art Ð and it is art, make no mistake Ð writing all sorts of blather about how he strips the adult century bare by his cutting up of vinyl records and pasting them together with parts from other vinyl records, they never seem to mention that these sound collages of his are charming, very human, and quite often intentionally hilarious."

Marclay has performed and recorded both solo and in collaboration with many musicians, including John Zorn, William Hooker, Elliott Sharp, Otomo Yoshihide, Butch Morris, Shelley Hirsch, Flo Kaufmann and Crevice; he has also performed with the group Sonic Youth, and in other projects with Sonic Youth's members."

"Along with his work as part of the acclaimed art/punk rock band Sonic Youth, Thurston Moore [b. born July 25, 1958] also pursued numerous solo and side projects, including Even Worse and the Dim Stars with Richard Hell. His first solo album, 1994's Psychic Hearts, featuring ex-Half Japanese guitarist Tim Foljahn and Sonic Youth drummer Steve Shelley, had an appropriately offhand feel but was far from sloppy. Along with carrying Sonic Youth into the 2000s, Moore collaborated with artists including DJ Spooky and Nels Cline, wrote music reviews and other pieces for Arthur magazine, and issued a book, Mix Tape: The Art of Cassette Culture, in 2005. His second song-based album, Trees Outside of the Academy, arrived in 2007, and featured largely acoustic arrangements and cameos by Shelley, Samara Lubelski, and Dinosaur Jr.'s J Mascis. In 2010, Moore guested on the Hat City Intuitive's A Ticket for Decay and began laying the foundation for another solo effort, Demolished Thoughts, which appeared the following year.

Following Moore's separation from bandmate, wife, and partner Kim Gordon in late 2011, Sonic Youth was put on indefinite pause. Nevertheless, Moore and Gordon collaborated with Yoko Ono the following year on the album YOKOKIMTHURSTON. By 2012, Moore had begun touring and recording with new act Chelsea Light Moving, as well as joining black metal group Twilight on guitar. The year 2013 saw the release of @, a collaborative album of sax/guitar improvisations with fellow N.Y.C. fringe dweller John Zorn. Arriving in 2014, The Best Day saw Moore shedding the softer acoustic moods of Demolished Thoughts for a return to his signature rock sprawl and daydreamy lyrics. Two years later, he issued the single "Feel It in Your Guts," which was available to anyone who donated to Bernie Sanders' presidential campaign. For 2017's Rock n Roll Consciousness, Moore reunited with his backing band for The Best Day -- Sonic Youth drummer Shelley, My Bloody Valentine bassist Deb Googe, and Nought guitarist James Sedwards -- on a mystically inspired set of songs."

"Lee Mark Ranaldo (born February 3, 1956) is an American musician, singer-songwriter, guitarist, writer, visual artist and record producer, best known as a co-founder of the alternative rock band Sonic Youth. In 2004, Rolling Stone ranked Ranaldo at number 33 on its "Greatest Guitarists of All Time" list. In May 2012, Spin published a staff selected top 100 guitarist list, ranking Ranaldo and his Sonic Youth bandmate Thurston Moore together at number 1.

Ranaldo was born in Glen Cove, Long Island, studied art and graduated from Binghamton University. He has three sons, Cody, Sage and Frey, and is married twice, first with Amanda Linn in 1981 but later divorced, and now with experimental artist Leah Singer.

Ranaldo started his career in New York in several bands, and joined the electric guitar orchestra of Glenn Branca. In this orchestra he played mainly electric guitar, but also some of Branca's harmonic guitars Branca had designed and built himself. In 1981, he and David Linton briefly joined the band Plus Instruments formed by Truus de Groot. With this line-up they recorded the album February - April 1981, released on the Dutch Kremlin label. After the release of the album, Ranaldo left the band and started Sonic Youth with Thurston Moore and Kim Gordon."
