Composer William Brittelle has shared the full score for and story behind "Forbidden Colors," the fifth track from his new album, Spiritual America, out now on Nonesuch/New Amsterdam Records. On the album, Wye Oak, Brooklyn Youth Chorus, and the Metropolis Ensemble perform a genre-defying electro-acoustic song cycle written by Brittelle, who works to reconcile his youth in a conservative Christian household with his adult life as an "agnostic Buddhist." Brittelle co-produced the album with Zach Hanson, who mixed it as well.
