Here is a guy DJing some good early Trance back in 1994, from a small, unknown European club.
But he has no arms and is doing it all with his feet.
05:05 - mix starts, upfader goes up for the incoming track being mixed in
06:39 - mix finishes
06:41 - removes record and swaps it with feet
06:52 - bang! there it is (with a flourish from the foot)
07:27 - bang! another flourish
07:30 - yep I'll just take another record with my toes thanks and cue it up.
And all of the tracks are awesome - I wish I knew what they were, especially the track at 9mins...
Please don't ask me how I found this. But hats off to the guy - awesome.
