Care to see how four players jam together in the upcoming Rock Band? Gamespot has had footage of a quartet taking on Welcome to the Jungle by Guns n' Roses.
The two guitarists here aren't using the new Fender strat replicas and a microphone is nothing new, but seeing the drums in action and how they'd be implemented on screen (check out the
right middle column) is interesting. And yes, you too will be required to make those faces when you play the game.
Update: The video has been taken down from Gamespot, but quazi has found a copy on YouTube. Footage embedded after the break.
