Boy Erased, a new film starring Lucas Hedges as a young man forced into gay conversion therapy, hits theaters November 2. In anticipation, the first cut from its soundtrack, a collaboration between Troye Sivan and Jónsi, was released today. "Revelation" matches the devotional intimacy of a Sivan ballad against the sweeping atmosphere of Jónsi's music. Sivan also stars in the movie, alongside Nicole Kidman and Russell Crowe.
