A reminder about the Maria Bachman violin recital at Penn tomorrow evening, Tuesday, March 29. She and pianist John Klibonoff will play two Philadelphia premieres:  a set of Three Pieces by Paul Moravec, and a Sonata by Philip Glass; a world premiere, The Flight of the Red Sea Swallow, by Penn professor Jay Reise; and the Sonata by the late George Rochberg, who was long a Penn faculty member. George wrote the sonata for Maria. The program is at Amado Recital Hall in Irvine Auditorium, 34th and Spruce in Philadelphia. The concert is presented by Penn Contemporary Music.
