With members of Rage Against the Machine, B-Real of Cypress Hill and Chuck D of Public Enemy in their ranks, Prophets of Rage are already a supergroup. At their Toronto concert at the Molson Amphitheatre last night, the group kicked it up another notch by having Dave Grohl join them on stage.

The Foo Fighter joined Prophets of Rage for their performance of MC5's hardcore classic, "Kick Out the Jams," at a show that was already being broadcast on the internet to a global audience from the group's official Facebook page.

Prophets of Rage are currently on their Make America Rage Again tour and will release their debut EP, The Party's Over, later this week.
