Over the past few years, the Police drummer Stewart Copeland has arranged jam sessions in his studio featuring a ton of big names in rock, and he’s taken to putting the result of these sessions on Youtube for all to see. His latest jam session was attended by the typical array of stars: South Park creator Matt Stone played drums (not for the first time, either), as did Rush’s Neil Peart and Tool’s Danny Carey. Vertical Horizon frontman Matt Scannell was on bass, Copeland on guitar, and a few people were brought in at a later date to add some horns to the jam. Watch below.
