Rammelzee vs. K-Rob - Beat Bop
Buy Ego Trip's The Big Playback
This song is probably more known for it's connection to Jean-Michel Basquiat than for the actual music. Basquiat produced the song and did the cover artwork. However, the song's not that bad either. This early concept song is ten plus minutes long and features some nasally rhyming from Rammelzee. This song is available on Ego Trip's The Big Playback, which seems to be out of print. You can pick it up used for very cheap (< $1).
An unrelated blog note: I like comments, so if you download the song, please leave a comment. It makes me happy.
