Music Director Susan Medley previews the PCC's "Three B's" concerts on March 2 & 3. She highlights the diversity of styles, notes the three Hallelujahs in Bach's Cantata #4, sings the praises of Brahms' Schicksalslied which resembles the composer's German Requiem, and describes how Beethoven's Choral Fantasy was a prototype for the Ode to Joy. Medley also talks about the choir's upcoming New York City debut at St. John the Divine.
