French pianist Helene Grimaud returns to play the Piano Concerto #1 by Johannes Brahms. Her new recording of both Brahms concertos has been released on the Deutsche Grammophon label. Ms. Grimaud is nearly as famous for her work as a naturalist as she is for her music – she co-founded the Wolf Conservation Center in upstate New York in 1996. She spoke in the Regency Room at Heinz Hall about her two careers.
