One day after three-day festival passes -- priced at a whopping $275 apiece -- sold out in a matter of minutes, Lollapalooza announced the highly-anticipated lineup for its Chicago-based festival early Wednesday morning.
The July 31-Aug. 2 fest in Grant Park will feature headliners Paul McCartney, Metallica and Florence + the Machine. This will mark McCartney's Lollapalooza debut.
Other highlights of the bill include Sam Smith, Alabama Shakes, Bassnectar, The Weeknd, Kid Cudi, Of Monsters and Men, Alt-J and TV on the Radio.
Though three-day tickets to the festival are already sold out, $110 single-day passes go on sale at 10 a.m. CT on Wednesday.
