Okay, there was disco too, but funk was the father of disco (yeah, I'm ready for that argument). This album is a great addition to the well-rounded collection I know you desire to have.

Curtis Mayfield isn't so much a household name (although he was much better known in the 70's), but he is one of the definitive sounds of the music that was the 70's.
