You know when you're watching a band, and the bassist turns to the drummer, and they make eye contact, and it looks like they connect? Yeah, that's all fake and choreographed. Add that to the show.
Sometimes, showmanship can make even the most boring parts fun.
Watch Metal Mania on VH1 Classic late Saturday nights. If you don't get it, it's on their website. Check out the drummers in the 80's videos. You don't have to dress or sound like them, but they put on a hell of a show. Channel your inner Tommy Lee!
