On Sunday afternoon, the Delray String Quartet offered a fine contemporary example of serious string-quartet writing with a performance of the String Quartet No. 6 (Addio) by the American composer Richard Danielpour. It is one of three string quartets by the composer that the Delray will record in May, including his Seventh, which the quartet commissioned from him. The Delray played this work with clear commitment and passion. Everything sounded well-rehearsed, and the foursome were particularly good in the hymn sections, when they displayed a kind of ensemble unity that allowed the music’s full expressive weight to come through. The Delray’s relationship with Richard Danielpour builds on its earlier collaboration with another South Florida-rooted contemporary composer, Kenneth Fuchs, whose Fifth Quartet was written for this ensemble. In doing these works, the Delray is making its own significant contribution to the cause of new American classical music, and to the profile of the arts in South Florida, for which residents here owe them our thanks.
