SANTA BARBARA – – UCSB Arts & Lectures presents Kronos Quartet | Five Decades on Wednesday, April 24 at 7:30 p.m. at Campbell Hall. For 50 years, San Francisco’s Kronos Quartet has challenged and reimagined what a string quartet can be, centering its work around the key issues of our time. Kronos has commissioned, performed and recorded works that engage with topics such as war and destruction, the climate crisis, social injustice and spirituality. Now, the multi-Grammy Award-winning quartet marks its anniversary with a program of new commissions, signature works from its vast repertoire and pieces from its Fifty for the Future project.
