The music I play in my car tends towards being high energy music, whether it be metal (e.g. Motorhead), techno (e.g. Dyewitness), or high-speed pop (e.g. early XTC). Of the live bands I've seen, the one with the highest intensity would probably be The Datsuns, back in 2000 when they released their first single (though the drummer of The Melvins gets extra points for the fastest drumming I've ever seen at a gig).
However, I guess it all depends on what you're into.
