I would say learning some Green Day or AC/DC would be a good idea. Or, if anything else, get very familiar with their music if you aren't already.

Izzy had a good point. A scene from Back to the Future comes to mind, where Marty is playing with a 50's band and breaks into an Eddie Van Halen type solo. That's what you *don't* want to do. :-) Support what the band is playing and fit in style-wise with what they are doing. And don't show off - nobody likes a show off.
