To put it into context , this would have been underground dance music 20 years ago, and a quick glance would suggest these tracks all came out in the early 2000s from small dance labels, so I can guess the date of the mix would be correct, a lot of German label releases on the mix also, like dial records from Hamburg , I would go to Köln and Berlin about this time and hear this kind of music being played, and it was mind blowing.
