Arctic Monkeys played the first day of Lollapalooza yesterday (1 August), and you can watch their full set below.
The band's set drew heavily from their fifth album AM, as have most of their live shows since the album's release, but also featured older songs such as 'Fluorescent Adolescent' and 'I Bet You Look Good On The Dancefloor'.

Elsewhere, the festival got off to something of a controversial start yesterday, after Dev Hynes accused the festival's security of 'assaulting' him and his girlfriend Samantha Urbani, lead singer of the band Friends.
Other acts to perform on the festival's opening day included Lorde, Lykke Li, Chvrches, Bombay Bicycle Club and Warpaint.
Lollapalooza continues tonight with headliners Outkast, and comes to an end on Sunday night (3 August) with a headline set from Kings Of Leon.
