No I wasn't in any of the bands mentioned in this thread. I've been playing in bands for over 20 years though, I played in a doom/death metal band from 1991 to 1995 called Dead Serenade. We made two demos and then disbanded. Long story. Most of the DS members played with ND at one point or another, though.
I played in a technical speed/thrash metal band called Neurotoxin from 1991 to 1996 as well. Again, several demos were done, some appearances on compilations, etc., but that's about it. Joe Nunez, drummer for ND, was in that band with me as well.
Besides that I played with a bunch of miscellaneous other metal and non-metal bands.
Chicago area bands that I would deem as being influential or inspiring to me would be Devastation, Sindrome, Contagion, Maimed, Trouble, Tyrants Reign (actually I did play with these guys for a short time), Salems Cross, Znowhite, Zoetrope, Lethal Injection
