I'm so glad these have finally surfaced... For those not in the know, DJ Q-Bert & Yoga Frog used to put out Turntable TV on VHS (remember those?) back in the late 90's. They featured scratch footage, amongst other random funny bits and pieces.
These videos are legendary and are a part of turntablist culture. I've got a bunch of these sitting in a drawer somewhere, so I might have to convert them to digital at some point in the near future.
For now, sit back and enjoy!
