Let me clarify: I would have not gone for ICP's music, nor that of any offshoot band. But they've actually had really good hip-hop acts there the past couple of years, and I could imagine my younger self going for the drinking and drugs and (halfheartedly trying and failing to have) sex. Plus I remember being roped into a lot of terrible, trashy 90s music/camping/partying events by friends and relatives and having a decent enough time. I can't imagine the crowd was all that different at a Dead show in Buffalo or the campground at the Philly Folk Fest, or any number of Lollapaloozas, except maybe a smaller relative proportion of lowlives and pro wrestlers.
But then again, I did adamantly refuse to go to Woodstock '94, so I guess I had some standards.
