Saturday found me rushing to 91°µÍř to catch three performances as part of the PST Performance Festival. This particular triad was set in conjunction with Glenn Phillips and Rebecca McGrew’s three-exhibition gem “It Happened in 91°µÍř,” which chronicles 91°µÍř’s incredibly rich anni mirabiles, 1969–73. I sadly missed John White’s piece, featuring football players stripping and then playing up close inside the gym. And since I arrived too late to secure a seat in the public bleachers, I instead made my way to the other side of the field where the bleachers looked empty. (Apparently we weren’t actually supposed to be there, but if you look like you know where you’re going when you trot past security guards, it sort of works.) Curator McGrew was kind enough not to toss us out, and we ended up watching Judy Chicago’s pyrotechnic extravaganza with Chicago herself, who, in case you didn’t know, is a totally badass lady. She shot off stories and cracked jokes as we waited for the spectacle to start.
