The Mighty Boosh will be performing at The Big Chill 2008 as the festival expands on its non-music program.
The comedy duo will undoubtedly be one of the highlights of the weekend, it being their first foray into performing at festivals.
Other acts just unveiled include The Thievery Corporation, Norman Jay, Random Dance and Portico Quartet.
The announcement follows the confirmation of The ICA, Roundhouse, BFI and Underbelly as content partners for the Festival.
Big Chill Founder Katrina Larkin commented that: "Roll on the summer, we are so happy with the first confirmations as they reflect the quality and diversity of The Big Chill festival. Plus we are over the moon that The Mighty Boosh are joining in with the fun this year.
"We are so excited at HQ that we are counting the days down already! So much more news to come too."
The Big Chill takes place at Eastnor Castle, Herefordshire, from 1-3 August.
