For more than 30 years, the Kronos Quartet - David Harrington, John Sherba (violins), Hank Dutt (viola) and Jeffrey Zeigler (cello) - has pursued a singular artistic vision, combining a spirit of fearless exploration with a commitment to expanding the range and context of the string quartet. In the process, Kronos has become one of the most celebrated and influential groups of our time, performing thousands of concerts worldwide, releasing more than 40 recordings, collaborating with many of the world's most eclectic composers and performers from Terry Riley and Philip Glass to David Bowie, and commissioning hundreds of works and arrangements for string quartet. The Kronos Quartet has been featured prominently in such films as Requiem for a Dream, 21 Grams and Dracula, and has garnered numerous awards, including a Grammy for Best Chamber Music Performance (2004) and "Musicians of the Year" (2003) from Musical America.
