The concert began in mugginess, with the kind of slow build typical of Pearl Jam's longer concerts. Dressed in black, Vedder, Mike McCready, Stone Gossard, Jeff Ament and Matt Cameron entered with the simmering "Release" and some deep-album tracks, then the wistful "Elderly Woman Behind the Counter in a Small Town." Whispers were exchanged on stage shortly after 9 p.m., and pretty soon Vedder was telling the fans on the infield to move toward the grandstand to find shelter from the oncoming storm. The evacuation was orderly, the wait interminable. Within 30 minutes, the weather system had washed out the last half of the headlining set by Bjork at Union Park and the second half of Phish's concert at Northerly Island a few miles to the south of Wrigley.
