My old metal band got a legendary underground reputation for doing 2 house parties. The first was on a whim, some dumb party girl we all knew invited us to play. It was in the basement of some apartment/rundown business, and was completely filthy and unsafe. We get there early, there's people way too young to be partyin as hard as they were, I was probably the oldest person there by about 10 years. The first band was a Siblime-esque hippie band, pretty cool and chill. The band after that was a bubblegum punk band a la Blink 182 that went over with the girls really well. Then a couple folks tried an acoustic thing which was largely ignored. Then WE got to playin. The only really aggressive act there. We crank our amps as loud as they'd go, next thing we see is the entire place is moshing and everyone is just kicking the $hit outta one another. Bear in mind, the room was cinder blocks with wooden racks anchored to the walls in various places, surrounding this huge cast iron octopus boiler, a single light bulb hanging out of the ceiling. Those kids were so amped up we saw blood fly lol, literally. One kid got clotheslined by one of the boiler pipes and opened up a cut in his scalp, and he just kept right on wreckin house. We had the place roaring so loud the cops got called and cleared us all out. The whole party told everyone they knew in town about us and we became legends inside one night for causing things to get so rowdy lol. The 2nd house party was basically the same deal, but on halloween.
