Casting is giddily age blind, even for opera. Both Luisa (soprano Krassimira Stoyanova) and her true love, Rodolfo (tenor Joseph Calleja), look to be—however miraculously—at least as old as their fathers ( baritone Quinn Kelsey, a Lyric favorite, and bass-baritone Christian Van Horn). And why not? They all sound fabulous, as does mighty bass Soloman Howard, making his first Lyric appearance as the slimy Wurm, and mezzo-soprano Alisa Kolosova as the duchess Rodolfo’s father wants him to marry. Ryan Opera Center member Kathleen Felty aces her Lyric debut in a supporting role, and the dependably excellent Lyric Opera Chorus is on hand as peasants, nobles, and soldiers. v
