Lollapalooza have revealed their 2015 line-up and - with Paul McCartney, Metallica, Florence and The Machine, Sam Smith, Alt-J, Death From Above 1979 and more - it's as overwhelmingly great as we expected.
McCartney, Metallica and Florence will headline the Chicago festival, which takes place between 31 July and 2 August. Other notable acts include Tame Impala, The Weeknd, Tyler The Creator, Hot Chip, The War On Drugs, FKA twigs, Banks, Tove Lo, Flying Lotus, Django Django and First Aid Kit.
The festival originated as a tour of North America before reforming into its current format as a weekend festival in Grant Park, Chicago. It's since expanded beyond the US into Chile, Brazil, Argentina and - for the first time this year - Berlin.
The line-ups for each different festival location are entirely different, with The Libertines, Macklemore, Chvrches and Bastille set for Berlin.
