Kronos Quartet

Kronos Quartet is celebrating 40 years of playing music together — and to mark the occasion, they're playing a celebration concert at Carnegie Hall in New York tomorrow night. Since their founding, the San Francisco-based string quartet has become one of the most visible ensembles in classical music. The players have done it by championing new and underheard music, and by coming up with a business model that was unheard of for a chamber group four decades ago.

When you hear the name of guitarist and composer Bryce Dessner, you wouldn't be wrong to think immediately of hugely acclaimed indie-rock outfit The National. But he's also a stalwart of the new music scene.
