For nearly 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. Through its nonprofit organization, Kronos Performing Arts Association (KPAA), Kronos has commissioned more than 1,000 works and arrangements for quartet. Kronos has received more than 40 awards, including the Polar Music, Avery Fisher, and Edison Klassiek Oeuvre Prizes. Integral to Kronos’ work is a series of long-running commissioning collaborations with hundreds of composers worldwide, including Terry Riley, Aleksandra Vrebalov, Tanya Tagaq, Philip Glass, inti figgis-vizueta, FodéLassana Diabaté, and Steve Reich. In its most ambitious commissioning effort to date, KPAA has recently completed50 for the Future: The Kronos Learning Repertoire. Through this initiative, Kronos has commissioned—and distributed online for free—50 new string quartet works written by composers from around the world. In recordings, Kronos has collaborated with artists including Wu Man, Zakir Hussain, Asha Bhosle, MahsaVahdat, and Nine Inch Nails. Kronos has performed live with the likes of Paul McCartney, Allen Ginsberg,Rokia Traoré, David Bowie, Rhiannon Giddens, Caetano Veloso, and The National, among many others. The quartet tours for several months each year, appearing in celebrated venues, including Carnegie Hall (NewYork), Palacio de Bellas Artes (Mexico City), the Barbican (London), the Muziekgebouw (Amsterdam), Shanghai Concert Hall, Suntory Hall (Tokyo), and the Sydney Opera House. Kronos’ expansive discography on Nonesuch includes three Grammy-winning albums—Terry Riley’s Sun Rings (2019), Landfall with Laurie Anderson (2018), and Alban Berg’s Lyric Suite (2003)—along with dozens of other acclaimed releases. Kronos’ most recent recording isMỹLai (2022), an opera by Jonathan Berger and Harriet Scott Chessman. Kronos’ work has also featured prominently in many films, including the “life documentary” A Thousand Thoughts, written and directed by Sam Green and Joe Bini, which premiered at the Sundance Film Festival in 2018. Based in San Francisco, the nonprofit KPAA staff manages all aspects of Kronos’ work, including commissioning, concert tours and local performances, recordings, education programs, and an annual KronosFestival in San Francisco.
