I had quite a lot of mid to late 80s Goa DJ tapes that I downloaded from soulseek 20 years ago. DJs like Goa Gil. Maybe 20 or so mixes. They were a great melting pot of alternative dance and electronic and synth pop and tempo wise generally much slower than the banging ones I have heard from the early 90s. I would compare them with some of the mid 80s Ibiza tapes I’ve heard or pre New Beat era Belgium. A lot of Yello, Eurythmics, Blancmange, Depeche Mode, EBM, Koto etc etc.
Sadly I lost them all when my old hard drive literally melted a few years back but I’m sure they’re still out there on YouTube or torrent sites.
