For over 45 years, San Francisco’s Kronos Quartet—David Harrington (violin), John Sherba (violin), Hank Dutt (viola) and Sunny Yang (cello)—has combined a spirit of fearless exploration with a commitment to continually reimagine the string quartet experience. In the process, Kronos has become one of the world’s most celebrated and influential ensembles, performing thousands of concerts, releasing more than 60 recordings, collaborating with an eclectic mix of composers and performers, and commissioning over 1000 works and arrangements for string quartet. The group has won over 40 awards, including two Grammys, the prestigious Polar Music and Avery Fisher Prizes, and Edison Klassiek Oeuvreprijs. The nonprofit Kronos Performing Arts Association manages all aspects of Kronos’ work, including the commissioning of new works, concert tours and home season performances, education programs and the annual Kronos Festival. In 2015, Kronos launched 50 for the Future: The Kronos Learning Repertoire, an education and legacy project that is commissioning—and distributing online for free—50 new works for string quartet composed by 25 women and 25 men.
