We want something intimidating with a dirty bassline, start this at 55 seconds which can be the build up, then as soon as the beat drops there should be a massive firework bang off at the end of the tunnel and the players run out. It might put some of those quiet old farts off who 'sshhh' you and tell you to sit down when trying to create atmosphere. Everyones a winner!!
