Diamanda Galas, famed avant-garde performance artist, composer, keyboardist, and vocalist has been described as “capable of the most unnerving vocal terror.” Musicologist Susan McClary writes that Galas “heralds a new moment in the history of musical representation.” Focusing on themes of suffering, injustice and despair, her works are characterized by visceral shrieks and wails reminiscent of glossolalia, or “tongues.” She has collaborated with Led Zeppelin bassist John Paul Jones, and her work has appeared in such mainstream films as Natural Born Killers and Francis Ford Coppola’s Dracula.

This month Galas is performing at Cannibal Club on Friday and Saturday nights.
