First show I can remember was madball, earth crisis, hatebreed, and skarhead in '97 in dc.
Saw bad brains when they first changed their name to soul brains, the pilfers opened for them and were awesome.
The dc superbowl of hc in like 98 or 99 had 25 ta life when they were still good, next step up, murphys law, dying fetus(with such great songs as "rape you mom and kill your fucking dog"),and a bunch other coil bands I don't remember.
Sick of it all was always intense.
Since living in Chicago for the last 12 years, got to see rise against before they turned pop, arma angelus(awesome hc band with Pete went before the lame fallout boy stuff)
I could go on for days
