Here's the official synopsis:

Located alongside the Tennessee River, Muscle Shoals, Alabama is the unlikely breeding ground for some of America's most creative and defiant music. Under the spiritual influence of the "Singing River," as Native Americans called it, the music of Muscle Shoals has helped create some of the most important and resonant songs of all time. At its heart is Rick Hall, who founded FAME Studios. He is responsible for creating the "Muscle Shoals sound" and the Swampers, the house band at FAME that eventually left to start their own successful studio, known as Muscle Shoals Sound. Greg Allman, Bono, Clarence Carter, Mick Jagger, Etta James, Alicia Keys, Keith Richards, Percy Sledge and others bear witness to Muscle Shoals' magnetism, mystery and why it remains influential today.
