Talea Ensemble at Library of Congress brings a paradise to the ears

The Library of Congress is famous for showcasing the world's best chamber music groups -- its concert series at the Coolidge Auditorium is one of the District's must-hear events. But the Library is also a quiet champion of new music from living composers, and on Friday night, those roles came together in a performance by the New York-based Talea Ensemble, featuring four new cutting-edge, strikingly original works, three of them commissioned by the library itself.
