Metallica Behind the Scenes of Band’s Salesforce Performance [Video]
Go into the rehearsal truck, where the band warms up for the show -- and in this case, makes fun of Lars' new warm-up drum kit.
It's an electronic drum kit, so they can play anywhere and not make noise. But the other guys in the band are teasing Lars about playing some Pet Shop Boys songs on it.
Then they play some Metallica, and hit the stage for more!
Lars uses a real drum kit on stage, in case you're wondering.
