Its Club 6400 night. if you aren;t aware of what Club 6400 was, you can check it out here, http://www.club6400.com/
Admittedly, never made it into the club, but one night a week was always broadcasted on a Radio Station, used to have a ton of Cassette tapes of the music. Why did i not go to Club 6400? well usually because i was either at this palce http://www.numbersnightclub.com/. Plus it was kind of a frat club that wasn't really my scene.
