It would be an injustice for me to even begin to explain the significance of Larry Levan and the Paradise Garage to dance music's history and culture. Instead, you need to watch this documentary (called Maestro) that tells the story of a truly iconic and influential DJ and the club whose reputation he shaped.
After you've taken the time to watch this (you can find the other parts on youtube), you'll find tons of Larry's music out there for possibly the most heralded DJ in the history of dance music culture.
Larry Levan. One Love.
