Yes - it's a must have if you're interested in that era...definitely has the best shots you're every likely to see of the garage.
It's mainly a feature with lots of talking heads going "larry levan this...larry levan that..." etc etc.
Great viewing but not very musically orientated.
I preferred the Godfather of Disco but it hasn't been released on DVD yet - can't wait for that one!
But tbh they compliment each other really well because the GoD is much more about specific releases/Tom Moulton/Mel Cheran etc etc.
