Lollapalooza, 1 and 2, were similar. Eddie would climb the scaffolding, and the it was out doors, so it was all dirt, and HOT, and when everyone went nuts, security used fire hoses, which turned the first 100 feet off the stage, to mud.The most people I've ever seen get fucked up at a show was Pearl Jam if you can believe that. Also in CT (Hartford).
Security roughed up some kid and Eddie wasn't having it--jumped into the crowd. Seats emptied and the audience rushed the stage, including my punk friend and I who were not used to sitting down for shows.
The crush up front got intense, but the real problem was the seats. People were standing on them and between them--it was crazy. Then the seats started failing a row at a time, a few dozen people would go down, and a few dozen more would fall on top of them. It happened over and over again, followed by a procession of limp bodies passed over the heads of the crowd to the stage where security took them away.
At 1pm, in the heat, it felt great. When the sun went down at 9, it was like being stuck on top of the Adirondacks with a York Peppermint Patty.
