One of the greatest voices in American music history has been silenced. Levi Stubbs, lead singer of The Four Tops, passed away today at the age of 72.

While folks of a certain age might only know Stubbs as the voice of Audrey the man-eating plant in The Little Shop of Horrors and even younger fans might only know Levi’s voice from the song Are You Man Enough, which was featured in the film Superbad, most music lovers know him as one of the most powerful singers Motown ever produced.
