Three "songs" appear on the tape, entitled: Vegas, Joe's and Cave, but we assume those are not real songs, but just ad hoc names.
Note from unknown source reads "Bruce Hornsby later reminisced, 'Branford Marsalis, Jerry Garcia, Rob Wasserman and I did some crazy space music for some Levi's jeans ads that Spike Lee was making in 1991. We were out there rehearsing at Front Street, the old Dead studio when I was playing with them, and we recorded this crazy space music that he used."
