The human voice is (very probably, we’re pretty darn sure) the first classical music instrument. Grammy-nominated producer, choral and orchestral instructor, and artistic director of Grace Song, Inc., Keith Weber takes us on a journey through the evolution of choral work. He also explains why choir singers are generally in way less peril than opera singers. Audio production for this episode by Todd “Tasty” Hulslander with smart-mouthed comebacks from Dacia Clay.
