Liars can occasionally be mistaken for an experimental band when you listen to their records. But seen live there's no mistaking that they're a great band of a really traditional sort, even when they're performing not-very-traditional rock songs. They bring an instrument-walloping, body-tossing intensity to their gigs, the kind of abandon that makes it hard to just sit back and check your Twitter feed. Even when the rhythms get delicate and the guitars get dreamy, when the music turns more art-rock than art-punk, there's a certain slightly mocking theatrical grandeur to the band's delivery. They understand that an audience, who could just as easily be listening to this spacey stuff while sacked out on the couch at home, needs to be entertained.
