Radiohead capped off a hot first day (Aug. 1) at the Lollapalooza music festival at Chicago's Grant Park, its set drawing heavily from its new "In Rainbows" and 1997's revered "OK Computer." A packed sea of 75,000 fans, which fanned out hundreds of yards from the stage, sang along to favorites like "The National Anthem," "No Surprises" and the title track from 1995's "The Bends."
