The year is 1985. The location is the Wyandanch High School gymnasium. The performers are Kid Wizard, Biz Markie, MC Chilly Dawg, Grandwizard BMC & DJ Fantasy. Oh yeah, Kid Wizard is the God Rakim Allah!
This one is crazy to me simply for that reason alone. This was just before Ra and Eric B made their debut and Rakim, uh, I mean Kid Wizard, spits his '7 MC's" verse. I've included the recording of both the full party as well as just Ra's appearance. Doesn't get much more nerdy on the rap tip than this one. Thanks to OldSchoolHipHopTapes for being so incredible and jackable!
