Performance art *bah*
Hardly Performance Art. In its heyday, this was an excellent form of expression and done by artists with intent and almost always a message to take away. Heck, Whoopie Goldberg was doing performance art in our own local Sushi Gallery before she moved to San Francisco and, a year later, appeared in The Color Purple.
Rachel Rosenthal, Yoko Ono, The Kipper Kids, Paul Best...the list goes on. Oh, those were the days for serious performance. Although I admit that these little mob gatherings have their appeal, like anything else loosely organized and involving the general public on a regular basis for no purpose whatsoever than to be involved in a "rumble", these soon will be cracked down upon, banned, and otherwise distrupted when a few jerks ruin the fun, and the cops start getting hip to the e-mail lists and show up well before the gathering.
