Adam Guettel’s “Myths and Hymns” headlines this year’s MasterVoices
Floyd Collins — and seven years before The Light in the Piazza would light up Broadway and earn him two Tony Awards in the process — Adam Guettel took a break from musicals to pursue something a little different.Inspired by two very different sources — the Greek myths of Icarus, Pegasus, Hero, Leander, and Sisyphus and the lyrics he found in a 19th-Century Presbyterian hymnal — Saturn Returns, as it was originally called, was a theatrical song cycle exploring the nature of faith and longing in a secular world.Musically, the work features a diverse mix of 23 original songs, veering from electronic jazz to piano balladry, gospel to musical theater.
