Lollapalooza had barely started its opening day when it had its first major headline. Only 20 minutes into a set scheduled for an hour during the Chicago festival's first day, Liam Gallagher walked offstage.

According to, Gallagher opened with two songs he made famous with Oasis, "Rock 'n' Roll Star" and "Morning Glory," before moving on to two cuts from his upcoming As You Were, the single "Wall of Glass" and "Greedy Soul," and then leaving the stage. Greg Kot, music critic for the Chicago Tribune, said that Gallagher ended the show without any explanation.

At 5:30PM Central, the time his set was supposed to end, Gallagher sent out a tweet in which he said vocal problems were the reason he cut his set short. "Sorry to the people who turned up for the gig in Chicago lollapalooza," he wrote, "had a difficult gig last night which f---ed my voice. I'm gutted."

The gig was one of Lollapalooza's official pre-parties at Park West, a small club on the city's North Side. Gallagher performed 13 songs, with seven coming from As You Were, five from Oasis' catalog and a new one called "Eh La" that he premiered in New York over the weekend.

Arriving Oct. 6, As You Were is Gallagher's first album as a solo artist after fronting Oasis for seven records and two with Beady Eye. He'll be touring North America beginning Nov. 13 in San Francisco and ending on Nov. 30 in Philadelphia. Chicago-based fans who want a full set from him can catch him at the Riviera on Nov. 21.
