Probably the must unsung unheard of session men in rock history. I'll bet a good portion of the listening public thought they were all funky black dudes playing.....not four average rural white guys. ( And I don't imply anything racist at all by that statement). You could say they were funk before funk was cool in many respects. They came up with a lot of funky riffs in their time. You probably heard them play on lots of records and never realized who they were, where they were from or how they got to be in the studio at all. Independent Lens had a good doc on them that I watched the other day. Very good. Recommended. Feel free to post any info you have on these guys and Rick Hall.
