In 2015, the Kronos Performing Arts Association (KPAA), the San Francisco-based non-profit organization of the Kronos Quartet launched Kronos Fifty for the Future, an education and legacy project that has commissioned—and distributed for free—the first learning library of contemporary repertoire for string quartet. Fifty new works have been commissioned, and scores and parts, as well as supplemental learning materials that include recordings, videos, performance notes, and composer interviews, are available on kronosquartet.org. Lead partner Carnegie Hall and an adventurous group of project partners, including presenters, academic institutions, foundations, and individuals, have joined forces with KPAA to support this exciting program.
