Kronos Quartet

Kronos Quartet is an American string quartet founded in Seattle in 1973 by the violinist David Harrington, and based in San Francisco since 1978. The group concentrates on contemporary repertoire and has commissioned new pieces from composers in many countries and traditions. Kronos Quartet has recorded mainly for Nonesuch, where it issued Black Angels in 1990 (built around George Crumb's piece of that name) and Kronos Quartet Performs Philip Glass in 1995. Composers who have written for the group include Terry Riley, Steve Reich, John Adams, Arvo Pärt and Henryk Górecki.
