Bard College is an interesting cultural melting pot, open to all sorts of weird innovation at the same time that it honors, preserves and sometimes rescues from obscurity the classical canon – especially when it comes to music. Since 1979 it has served as home base to the Hudson Valley Chamber Music Circle (HVCMC), now 66 years old. And each June, the HVCMC presents a series of concerts at Bard’s Olin Hall, never failing to bring top-tier names from the chamber music pantheon to Annandale-on-Hudson. (It undoubtedly helps that superstars Jaime Laredo and Sharon Robinson are the Circle’s current artistic directors.)
