For the past six years, Grant Park in Chicago has served as the sacred Lollapalooza upon which pop idols are worshipped and lesser known are given opportunity to prove their mettle. For three solid days, bands such as Devo, Edward Sharpe and the Magnetic Zeros, The National, and The Dirty Projector, earned their places on the honor roll. But the highlights were the headliners, and Arcade Fire elicited surges of awe and were just spectacular.
