Ash first burst on the scene as an exuberant teenage kick of a band. Writing buzzsaw punk-pop anthems about high summer fun and sci-fi, they were easy to love. Now presumably all grown up, Ash have lately been ringing the changes: relocating to New York, parting company with guitarist Charlotte Hatherley to revert to a trio, and announcing that their fifth album, Twilight of the Innocents, will be their last before they henceforth release only singles "for the digital age".

The album has a new air of introspection, but is still alive with visceral thrills. Songwriter/vocalist Tim Wheeler retains a lightness of touch that means even his accounts of long, dark nights of the soul are giddy with zest and infectious melodies. I Started a Fire is reminiscent of early U2, while single You Can't Have It All has the edgy grandeur of Echo and the Bunnymen, confirming them as masters of wide-eyed angst.

Still barely 30, they attack their oldies with relish; Girl from Mars is as sharp as in its Britpop heyday. Ash's flush of youth is passing but as long as Wheeler remains so keenly prolific, they will carry on doing just fine.
