The San Francisco Gay Men's Chorus honored both Mary Lambert and Tyler Glenn of Neon Trees last Saturday at the 40th Season Crescendo Gala for using their voices as agents of change. As part of the evening's theme of family, their mothers joined them for the evening and presented their awards. Two-time Grammy Award nominee Lambert performed her hit "She Keeps Me Warm," and Glenn performed his band's track "Animal." The show closed with Bob the Drag Queen's upbeat "Purse First" number.
