Mos Def Bringing Groove to 2010 Glastonbury

Glastonbury is on of the U.K.'s most epic festivals. Celebrating its 40th anniversary this year from June 24-27, promoters are slowly leaking the names of 600 acts expected to perform across a ton of stages over the course of four long days. One of the biggest developments is a new stage that's being called the West Holts. The name of the game here is "groove-heavy" music, so you'll be getting performances from a wide range of artists including Mos Def, George Clinton and the Parliament Funkadelic, Brother Ali and a tribute to the late, great Fela Kuti.

"We're going back to the real roots of Worthy Farm and its history with the name change for the stage," explained Glastonbury founder Michael Eavis in a press statement. "West Holts was a 'halt' originally; one of the two places where we had to open the level crossing gates across the old railway line to get the cattle through for milking. It was a fair walk up to the farm, just as it is now, and those cows took some driving!"

Tickets are already sold out, so hit your favorite online reseller if you want to attend. Major headliners already include U2, Stevie Wonder, Muse, Vampire Weekend and Jack Jackson. Other performers on the West Holts stage with Mos Def include the Brazilian tropicalia of Os Mutantes, the roots reggae of Toots and the Maytals and the freakish folk of Devendra Banhart.
