Brit award winners Arctic Monkeys will join Snow Patrol, The Killers and Razorlight in headlining this year's T In The Park.
Held in Balado in Perth, the three-day festival has secured a strong contingent of British acts, including Amy Winehouse, The Fratellis, James Morrison, Lily Allen, Babyshambles, Paulo Nutini and Kasabian.
Adding an international flair are the Scissor Sisters, My Chemical Romance, Kings Of Leon and the Goo Goo Dolls.
Only people with camping tickets will be able to see the Arctic Monkeys however, as, unlike previous years, they are only ticket holders who will have access to the arena on the Friday evening.
People will also have the choice this year of buying separate tickets for the Saturday and/or Sunday, a weekend ticket or a camping ticket.
Tickets go on sale from Saturday morning at 9am.
Over 170 artists will perform across 11 stages at this year's festival, which takes place on Friday July 6th Sunday 8th.
