It's a bit strange to listen to a tape where the Rock Steady performs. But still, you can hear (and feel) hip hop history on this snippet when Frosty Freeze, Crazy Legs, Take One and Ken Swift are asked to come to the stage. It's part of a tape where they perform with Kevie Kev, Whipper Whip and D.J. Theodore in Danceteria, 1982.
