The Rapture is kind of an exciting band. The terms "dance punk" and "disco punk" get thrown around a lot when people describe them. Those descriptions are apt in the right context.
The music on "out of the races and onto the tracks" is built around snarling garage guitar, screaming vocals, jumpy bass, and fast treble-y drums. The disco label undoubtedly refers to Matty Safer's upbeat bass work, and is most evident on the catchy, passionate title track. If you're the kind of person that'll buy a CD for one song, give track one a listen, then place your order.
If you're a little more discerning or budget conscious, you might want to be wary of the rest of the album. "Modern Romance" and "Caravan" combine obnoxious punk with early psychedelic influences more along the lines of Iron Butterfly and Ten Years After than Studio 54 denizens. "The Pop Song" offers a noise-pop build-up that disintegrates into falsetto misery.
The Rapture is a little hard to listen to but also promising. I wouldn't say that they're an incredibly original band (compare track one with Gang of Four's "Outside the Trains Don't Run on Time"), but with their melange of influences, they do some things no other band is doing. Worth a listen, but probably not a purchase for most music listeners.
