As an improvising musician he has found the line between composer and performer to be gray at best.

Elliott Sharp (b. Cleveland, Ohio, March 1, 1951) is an American multi-instrumentalist, composer, and performer who has personified the avant-garde experimental music scene in New York City for over thirty years. He has released over sixty-five recordings spanning the musical spectrum from blues, jazz, and orchestral music to noise, no wave rock, and techno music.

Sharp describes himself as a lifelong "science geek,"[1] having modified and created musical instruments from his teen years. He is an inveterate performer, both as a soloist (playing mainly guitar, saxophone and bass clarinet) and with a number of ensembles he has formed over the years, including the blues-oriented Terraplane and Orchestra Carbon. His compositions have been performed by the Symphony of the Hessischer Rundfunk, the Ensemble Modern, Continuum, the Orchestra of the SEM Ensemble, Kronos Quartet, Zeitkratzer, the Soldier String Quartet, and the Quintet of the Americas. He releases music under his own label (zOaR music) as well as punk label SST and downtown music labels such as Knitting Factory records and John Zorn's Tzadik label. Guitar Player magazine's 30th anniversary issue included Sharp among their list of "The Dirty Thirty - Pioneers and Trailblazers".

He has collaborated regularly with many people, including Zeena Parkins, Eric Mingus, Vernon Reid, Bobby Previte, Joey Baron, David Torn, Nels Cline, and Frances-Marie Uitti, as well as qawaali singer Nusrat Fateh Ali Khan, blues legend Hubert Sumlin, and Bachir Attar, leader of the Master Musicians of Jajouka.

Sharp attended Cornell University from 1969 to 1971, studying anthropology, music, and electronics. He completed his B.A. degree at Bard College in 1973, where he studied composition with Benjamin Boretz and Elie Yarden; jazz composition, improvisation, and ethnomusicology with Roswell Rudd; and physics and electronics with Burton Brody. In 1977 he received an M.A. from the University at Buffalo, where he studied composition with Morton Feldman and Lejaren Hiller, and ethnomusicology with Charles Keil.

He also curates the State of the Union compilations of one-minute tracks by experimental musicians, and produces records for numerous artists.

Sharp lives in lower Manhattan with designer/video artist Janene Higgins and their two children.
