British rockers Radiohead will join Tom Petty AND THE HEARTBREAKERS at this summer's (06) annual Bonnaroo Music + Arts Festival.

Beck, Elvis Costello, Damian Marley and The Neville Brothers are also signed up to play at the three-day camping festival which runs from 16-18 June.

Organisers have cut the 90,000 people capacity down by 10,000 to make the site, located on a 700-acre farm in Manchester, Tennessee more comfortable.

Bonnaroo, which began in 2002, has gained a respected reputation for attracting a diverse line-up of newcomers established artists.
