One of the better and more thoughtful Isaac Hayes compilations, Ultimate Isaac Hayes: Can You Dig It? is a three-disc (two CDs and one DVD) set that covers his years on Stax. There's a wide range of material here, from singles to deep album cuts, that provide a very representative look at these years, and Stax is even wise enough to include "I Stand Accused" and "Walk on By" in their full 12-minute versions. Only minor quibbles could be made with the selections. The third disc, a DVD, contains three songs performed by Hayes at Wattstax. And then there's the cherry -- er, some other spherical object -- on top: Hayes' performance of Chef's "Chocolate Salty Balls."
