Lollapalooza returned to Chicago this past weekend for three days of music throughout Grant Park. In contrast to past Lollapalooza festivals where heat has hovered in the 90s with high humidity, fans were blessed with temperatures in the 80s with relatively low humidity. The recently reactivated Strokes and Lady Gaga headlined Friday’s festivities with conflicting set times that saw many fans running between stages to catch portions of each performance. Lady Gaga—who played the festival three years ago and, by various accounts, had something of a trainwreck of a set for a handful of fans—often noted her triumphant return as headliner throughout her set.

Other highlights from the Friday included a sit in from Jeff Tweedy during Mavis Staples set for “You Are Not Alone” and “Only the Lord Knows,” the two tunes he penned for her latest album which he produced. Staples’ set also featured a rollicking take of The Band’s “The Weight.” Meanwhile, Devo also proved itself to be more than just a nostalgia act with a precise and upbeat set that heard the band running through new and old material including the ubiquitous “Whip It.” The Drive-By Truckers, The Black Keys, Jimmy Cliff, Chromeo, Hot Chip, Dirty Projectors and the New Pornographers and many other acts also performed earlier Friday.

Saturday’s entertainment started off strong with sets from the Morning Benders, The Soft Pack and Rogue Wave during the early afternoon. The fun, sing-along punk of Against Me! was early highlight followed by a mellow set from Grizzly Bear and an energized Metric. The night’s headliners, Green Day and Phoenix, provided entertaining (if anticipated) sets of music that didn’t stray far from their regular routines. Other highlights of the day included Dawes, Social Distortion, Edward Sharp and The Magnetic Zeros, Spoon and The xx.

The festival continues through tonight with headlining sets by Soundgarden and Arcade Fire.
