Rage Against The Machine have spoken for the first time about their reasons for reuniting for a one-off performance at this years Coachella Festival.

Besides admitting that the festival has been trying to get the band to appear "for as many years as they've had the festival," the group's guitarist, Tom Morello told MTV that the reason they've reformed was "to deliver a knockout blow to the Bush administration."

Morello explained: "This administration has done enough damage that it may take generations to undo. This is an administration that believes it's beyond the laws of the land, which is fine for emperors, but not so great for presidents."

The Californian festival takes place from the 27-29 April. The other headliners have been confirmed as Bjork, who opens the festival, and the Red Hot Chili Peppers.
