For 50 years, San Francisco’s Kronos Quartet—David Harrington (violin), John Sherba (violin), Hank Dutt (viola), and Paul Wiancko (cello)—has reimagined what the string quartet experience can be. One of the most celebrated and influential groups of our era, Kronos has given thousands of concerts worldwide, released more than 70 recordings, and collaborated with many of the world’s most accomplished composers and performers across many genres. Kronos has received more than 40 awards, including three Grammys and the Polar Music, Avery Fisher, and Edison Klassiek Oeuvre Prizes. Through its nonprofit organization, Kronos Performing Arts Association (KPAA), Kronos has commissioned more than 1,000 works and arrangements for quartet. KPAA also manages Kronos’ concert tours, local performances, recordings, and education programs, and produces an annual Kronos Festival in San Francisco. In its most ambitious commissioning effort to date, KPAA has recently completed Kronos Fifty for the Future. Through this initiative, Kronos has commissioned—and distributed online for free—50 new works for string quartet designed for students and emerging professionals, written by composers from around the world.
