In Conversations With Composers we talk with people who are creating new soundscapes that shape the ways we engage with life, art, and sacredness. In this first episode we speak with Patrick Cassidy about “The Mass”, his new major work for choir and organ. David Harris interviews Patrick and Christoph Bull to discuss the conception, creation and production of a major work recording during quarantine, and to delve into the mysteries of The Great Organs at First Church.
