Most of the bands I saw were 80s punk bands, because me and a bunch of other kids had access to a venue run by a local kid and we crowdsourced/DIY'd a bunch of folks. I'll probaby miss a few but if memory serves me correct:
The Circle Jerks, DOA, The Dayglo Abortions, Chaos UK, The Accused, The Teknakuller Raincoats, Fluid Waffle, Furnaceface, Death Sentence, 7 Seconds, I can't even remember many of the other ones...
Followed by Front 242 (twice), F**khead, New Kids On The Block (I had backstage passes because a friend was singing backup so why not?), Duran Duran, The Mission (Reading Rock Festival 1989, again, backstage passes), Download, KMFDM, Covenant, Peter Murphy, Segovia, those were the memorable big names.
