Bring your lunch and come hear Quartet Program participants perform on the Boulder Library's Third Tuesday Lunchtime Concert Series in their beautiful Canyon Theater. The Quartet Program, in its 41st year, in collaboration with the University of Colorado College of Music, is a four-week chamber music program which brings together some of the most gifted young performers from around the world.  Most American professional chamber music groups and orchestras today boast one or more QP alumnus. Formal Quartet Concerts will take place July 22-24 and Sonata Concerts July 28-31.  All performances are at 7:30 PM, in the Chamber Hall C199, CU College of Music.
