I was actually there, but the DJ didn't acknowledge anyone's presence behind the booth so I couldn't ask. I think that the music from 0:10 to 4:20 is a single song, but since I am not familiar with it, I don't know for sure. It is possible that it's multiple samples, but given the style of the set for the rest of the evening, that seems unlikely.
I'm most interested in that time frame, but the remaining 4 minutes were good too, so if anyone can shed any light on any of it, I'd be most appreciative. Cheers
