Today at 11 o'clock, the last in a series of three chamber music concerts by the Boston String Quartet will take place in Sanders Theatre. Sponsored by Mrs. Elizabeth Sprague Coolidge, these concerts have been unusually interesting because they have presented the works of Harvard composers exclusively. Today's program consists of a Trio by Walter Piston '24. Professor Hill's Quartet in C major, and a Piano Quintet in A major by John Alden Carpenter '97.
