Broken Records playing at the Big Chill in 2009
The Big Chill festival returns Eastnor Castle Deer park over the weekend of Thursday, 5 to Sunday, 8 August 2010.
40,000 people are expected at the Herefordshire site over the four day period.
This year, audiences will see headline sets from Bristol music production duo Massive Attack, futuristic and politically driven M.I.A and pop star Lily Allen.
Radiohead front man Thom Yorke, Kelis, Plan B, Newton Faulkner and The Mystery Jets are also set to appear at the festival alongside other chart and dance artists.
This is the first year that the promoter behind the Reading and Leeds Festivals will run the Big Chill, after buying out the company who used to be in charge of the event.
The takeover by Festival Republic secured the future of the festival after ChillFest went into administration earlier in the year.
The Big Chill claims to be 'more than a music festival', nevertheless organisers have secured a strong musical line up for the Eastnor crowds this year, including exclusive festival performances from Massive Attack and Thom Yorke.
Lily Allen first commandeered the public stage in July 2006
It's expected that Professor Green will make an unscheduled appearance on stage with Lily Allen during her Sunday night headline set.
The British rap artist confirmed his attendance in a twitter message to Lily which read "my gig got cancelled so I'm coming to Big Chill !!!!"
A secret special guest is scheduled for Friday evening on the main Deer Park stage.
Also performing at the festival are hyped dubstep supergroup Magnetic Man and alt-rock band Villagers, who have recently been nominated for this year's Mercury Music Prize.
