Wave Machines have just performed a sucessful gig at Glastonbury and they're back with good news for the fans. They are giving away 100 pairs of tickets for their gig at this month's iTunes Festival.

The show takes place on July 23rd at Freedom Studios, The Roundhouse, London. A winning entry gets you not only into the gig at 6.15pm but also a show by Graham Coxon, later that day, in the Roundhouse main space.

Just answer the following question to be in with a chance:

What stage did they play on Sunday at Glastonbury this year?

• a: John Peel Stage
• b: Queen's Head Stage
• c: Park Stage

Please send an email with your answer to: wavetickets@googlemail.com

The competition closes on 17th July. The winners will be contacted by iTunes with details of how to get their tickets.

Please note that the gig is exclusive to competition winners - you won't find tickets on sale anywhere, so be sure to enter!

Good luck if you do.
