William Powers
American bass-baritone William Powers is a native of Chicago who was taught and mentored by George London and Norman Treigle and made his New York City Opera debut in 1972. He has created many new roles in first performances and revivals, many of them rogues and villains. These include the villain Meyer Wolfsheim in Harbison's The Great Gatsby at New York Metropolitan Opera, and roles in Penderecki's Paradise Lost for Chicago Lyric Opera, Herrmann's Wuthering Heights for Portland and Stewart Copeland's Holy Blood and Crescent Moon for Cleveland. He has recorded two solo CDs for Centaur.
