I started listening to electronic dance music mid 80s.
Back then of course there was nothing called psy trance, not even trance.
First it was front242, skinny puppy, a split second, liasons dangerouse and similar stuff.
There was some 'synth' clubs in stockholm where I started going dancing to that stuff when I was 12yrs old
Then was acid, belgian new beat and body music that took my interest.
Lords of Acid - acid in the house and Acid Angels - ?? was the first couple of tracks I remember getting hooked on.
Trance came about, and I visited goa the first time 92.
The hottest stuff that season, that seem to me like it did much to help define goa trance was Eat Statics stuff. It was only spread on cassette tape (as most material back then) and only released a few years ago.....don't know the title of it though.
And overlords - sundown was the no1 sunrise tune...one of the first proper goa tunes to be released I would think, according to my definition anyway.
