In its most ambitious commissioning effort to date, KPAA has recently completed 50 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, Mahsa Vahdat, 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 (New York), 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), Landfallwith Laurie Anderson (2018), and Alban Berg’s Lyric Suite(2003)—along with dozens of other acclaimed releases. Kronos’ most recent recording is Mỹ Lai (2022), an opera by Jonathan Berger and Harriet Scott Chessman. Kronos’ work has also featured prominently in many films, including the “live 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 Kronos Festival in San Francisco.
