New York-based Christian Marclay has been a pioneering DJ since the 1970s, when he began to rock turntables and even old gramophones--bending, breaking and mixing records in the creation of a brand new instrument. Since then, in addition to DJing, he has exhibited his sound-based artwork internationally. "Ensemble" is a group exhibition of sound art at the ICA, which Marclay organized. Likening his approach to that of a composer rather than a curator, Marclay chose sculpture and installations based on their sound quality and sonic compatibility. An ambient sound environment resulted, with iconic works by such artists as Harry Bertoia, Yoko Ono and Michelangelo Pistoletto, mixed in with newer pieces. This publication includes a CD featuring a once-in-a-lifetime gathering of artist/musicians, including Shelly Hirsch, Alison Knowles, Alan Licht, Marina Rosenfeld and Mika Tajima "playing" the show.
