Much about ‘Beat Bop’ is shrouded in mystery. Who really produced it? Why was Jean-Michel Basquiat relegated from rapper on the track to drawing the cover and labels? What are they actually rapping about for most of the ten-minute length?

These questions, however, are all part of the enigma and rich legend surrounding a song that is an undisputed piece of true hip-hop genius. The combination of graffiti artist Rammellzee and rapper K-Rob is a potent one, with each MC adopting a persona - hustler and B-Boy respectively - that they maintain against an unusual swirling backdrop that must be one of the best instrumentals ever committed to wax.
