The headliners have been confirmed for the first three iTunes Festival shows.
Scissor Sisters (July 1), Tony Bennett (July 2) & Ozzy Osbourne (July 3) are to kick off this year's festivities at the Roundhouse.
Babydaddy of Scissor Sisters commented, "We can't wait to tickle your fancies with songs new and old as part of iTunes Festival. This will be our first performance ever at London's legendary Roundhouse, WOAH".
Tony Bennett says, "I'm thrilled that after playing two nights at London's famous Royal Albert Hall, where I've appeared so many times over the years, I'll be making my first appearance at the iTunes Festival at Camden's Roundhouse. I love performing my favourite music, the Great American Songbook, to audiences of every age - so playing to the iTunes crowd in such an intimate setting will be great fun. The audiences of Britain have been so warm and welcoming and I always look forward to coming here to perform."
"This has all the makings of a great gig," says Ozzy Osbourne who will release Scream, his first album in almost three years via Epic, on June 14. "I've never performed before at the legendary Roundhouse, and it'll be fantastic to do an intimate show there for the fans. We're also recording it, so if you can't make it to the gig, it'll be available for download on iTunes."
Listen again: Each performance will be recorded and sold exclusively on all 23 iTunes Stores worldwide. ITV will be broadcasting the best of the festival from the Roundhouse.
