The Kronos Quartet (often referred to as "Kronos" or "The Kronos") plays contemporary classical music and was founded in 1973 by violinist David Harrington. Since 1978, they are based in San Francisco, California. Since 1985, the quartet's music is released on Nonesuch Records. Early recordings by the quartet contain contemporary classical music and adaptations of more popular music, such as jazz and rock and roll. Since the 1980s, and especially with the release of Cadenza on the Night Plain, written as a collaboration between composer Terry Riley and the quartet, much of the quartet's repertoire and album releases contain music written especially for them, by composers such as Terry Riley, Kevin Volans, Henryk Górecki, and Ástor Piazzolla.
