Orbital are to play Isle of Wight's Bestival festival

Orbital are the first act to be announced for this year's Bestival, which takes place on the Isle of Wight between 6-9 September.

The electro group will be performing in the Big Top on the Sunday night of the annual festival.

This year's fancy dress theme has also been revealed as Wildlife.

Organiser and Radio 1 DJ Rob da Bank says he will reveal a new artist performing at Robin Hill Country Park every day for the next 12 days.

He said: "I've never been pestered so much on Twitter and even in clubs and on the street about who's playing Bestival this year so we thought we'd better start the proceedings.

"Legendary brothers of rave Paul and Phil Hartnoll aka Orbital are the first act who have self-announced themselves today…and what a classic to kick off on.

"As ever the theme of Bestival is a hotly debated topic - this year it's Wildlife - so maybe you're thinking foxes, badgers or flamingos or go a bit more lateral and think of wild men and women, hedonists and crazy people? It's an open book as ever. More news very soon!"

This year's camping capacity has been increased with a vintage cinema showing 1930s films also new for 2012.

Meanwhile Earth, Wind and Fire, Hot Chip, Kool and the Gang, Chic, Jimmy Cliff, Rizzle Kicks and Adam Ant will play Camp Bestival.

The family-friendly festival takes place at Lulworth Castle in Dorset between 26-29 July.
