Everyone think's their party is going to be the best. Some even shout about it on Facebook or their blog. A select few even air their boasts on the radio. A yet smaller number have anything to back up the claim.

Capital FM would appear to breathe the rarefied air of that elite handful that can 'walk the walk'. Capital FM's Summertime Ball, their party, takes place at Wembley Stadium - just about the biggest mud-free venue available anywhere. And the bill? Well, as you can see - not at all bad.

There's Coldplay, who seem to have asserted themselves as the world's premier indie-rock stadium fillers following last year's vainglorious Glastonbury appearance. On a good day, Chris Martin and co could probably fill Wembley by themselves but this time they're sharing the bill with some more music megastars including teen emperor Justin Bieber, and global pop firework Katy Perry.

But that's not the half of it. In the UK right now, you'd be pushed to find two hotter tickets than Ed Sheeran and Jessie J, yet here they are on the same card. The urban angle gets more than a cursory nod with sets from Example, Usher, Pitbull and Flo Rida, while pure pop is covered by The Wanted and the original American Idol Kelly Clarkson. Without exception, all headline acts.

These musical heavy hitters will be slugging it out for the headlines at Wembley Stadium on Saturday June 9th 2012. We have tickets available now, priced £49.99 for reserved seating and £55 for pitch standing. Platinum Package tickets, with reserved seating, hospitality, post-show party, goodie bags etc, are available for £199 (see vendor site for full details).

Capital FM are calling it this summer's biggest party. Hard to argue with that - and all for less than the price of a Lady Gaga ticket.
