I know, I know...Superfly and Shaft! kick ass. I'm not taking anything away from Curtis or Isaac, but for my money the grooviest blaxploitation soundtrack ever is Roy Ayers' Coffy. From top to bottom this soundtrack is funky, smooth, and indelibly groovy. The flick isn't so bad either. Pam Grier is smoldering is this classic revenge story. Check it out!
This is an excellent sampler of some choice cuts from the soundtrack. Dig it!
