Muscle Shoals is a good companion piece to Standing in the Shadows of Motown, both docs detail the unsung heroes who played on most of the songs we have come to know & love at some point in our lives. It details the ins & outs of what made the studio what it is by the hard scrabble direction of its owner & the various artists who came to record there & their memories on what made that studio so special. A nice piece of work.
