The legendary music festival Lollapalooza returned to Grant Park in Chicago this past weekend. This year’s line-up was eclectic and stacked. Some of the headlining acts included Metallica, Billy Strings, and Green Day among others.

90s alt band Porno for Pyros was one of the headliners on Sunday and busted out a cover of Zeppelin’s “when the Levee Breaks” with the Smashing Pumpkins’ Billy Cortana sitting in.
