This could be good so I pasted it from Xbox 360's blog:
Xtival is BACK!! [4 days ago]
And that means Xbox LIVE Gold membership is free for everyone! That’s right folks – the ultimate online party weekender returns to Xbox LIVE from 1st-4th May and this year we’re really spoiling you!
Fans will be treated to exclusive new content from Placebo, Fightstar, You Me at Six, In Case of Fire and much much more. Plus we’ve been working with our partners MSN to bring you recent footage from The Pussycat Dolls, which is not to be missed. All that plus you can watch LIVE concert footage from rock icons Queen, Bullet for My Valentine, Franz Ferdinand and The Pixies as well as films including the smash hit ‘The Dark Knight’.
But Xtival will offer more than just great music and movies! We’ve also got an exciting range of competitions and game add-ons for Lips, Halo Wars and Call of Duty: World at War, including an Xtival premium theme pack which will be available for everyone to download for free throughout the Xtival weekend. You will also have the chance to not only ‘Watch and Win’ but also ‘Play and Win’ in a series of online tournaments with exclusive prizes on offer, including the opportunity to win a pair of exclusive bling Lips microphones made with CRYSTALLIZED™ - Swarovski Elements!
Set your alarms, cancel your plans, block out your diaries and divert your mobile; Xtival is your chance to round up all your mates and hang out for 3 days to play, watch, listen and party!
