Missa Charles Darwin, was written for Grammy-nominated New York Polyphony and is structured on the standard liturgical Mass. Brown painstakingly translated DNA sequences and markers into musical phrases set to texts by Charles Darwin. In doing so, Brown simultaneously commemorates the scientist's genius while interrogating the relationship between faith and reason. All of Gregory's proceeds from this release are being donated to musical education charities including Chorus America, American Choral Directors Association, and the International Society for Music Education.
