I did not know about this Spike Lee-directed “unofficial” video for “White Lines.” He made it when he was a New York University film student back in 1983 (The World’s Best Ever brought this to my attention, so thank you!).
The video starred a then 22-year-old Laurence Fishburne as a disco dust drug pusher.
The song was written by Melle Mel and Sugar Hill label boss Sylvia Robinson (not Grandmaster Flash as they wanted people to believe). The famous sampled bassline comes from Liquid Liquid’s “Cavern.”
