Coldplay have been added to the bill for next month's iTunes Festival - joining frontman Chris Martin's wife, actress Gwyneth Paltrow.
The band are due to play Glastonbury Festival in 11 days but will play a more intimate show when they perform at London's Camden Roundhouse on July 22.
Also playing the month-long iTunes event will be Arctic Monkeys, Adele, Foo Fighters and Kasabian.
And the addition of Coldplay makes it something of a family affair as Gwyneth will also appear, hosting a session where she talks about her new cookery book.
Tickets for the nightly gigs are free to competition winners from www.itunesfestival.com.
Coldplay's Guy Berryman said: "The iTunes Festival always has a brilliant cross-section of artists but this year might just be the best ever.
"We're very proud to be part of such an impressive line-up."
Coldplay have just released their new single, Every Teardrop Is A Waterfall, ahead of the release of their fifth studio album.
Each live performance at the festival will be recorded and sold through iTunes.
