They recently released this documentary on BluRay and DVD. I was purchasing some other items on Amazon and unexpectedly came across this, so I bought the BR version. A good movie. Admittedly, I knew very little about Muscle Shoals. It is a small town in Alabama, not a recording studio per se. The actual studio that started it all is FAME Recording Studios. And subsequently the hit songs produced from the region became known by many as the "Muscle Shoals Sound".
Sound City, CA had a ton of famous acts recorded there. We find similar events coming from Muscle Shoals, AL. I had heard Lynyrd Skynyrd did record there. But did not know that Percy Sledge "When A Man Loves A Woman" was recorded there. Nor knew that Aretha Franklin, Paul Simon, Wilson Pickett, Rolling Stones, and many more also recorded there.
LA had the "Wrecking Crew". Here in the south they had the "Swampers". For the Lynyrd Skynyrd fans, tribute is mentioned in the song "Sweet Home Alabama".
Hopefully it will be available to stream from one of the internet services. It is worthwhile viewing for anyone interested in a bit of pop music history from the 60's and 70's.
