"Released at the tail end of the '60s, Hot Buttered Soul set the precedent for how soul would evolve in the early '70s, simultaneously establishing Isaac Hayes and the Bar-Kays as major forces within black music. Though not quite as definitive as Black Moses or as well-known as Shaft, Hot Buttered Soul remains an undeniably seminal record ... one of soul's timeless, landmark albums, the album that transformed Hayes into a lifelong icon".
