Always the most ambitious urchins of the east London scene, Razorlight were a Live8 success story, coming away with not just their reputation intact, but their fan base broadened. This being a Teenage Cancer Trust gig, ticket prices are higher than your average indie gig, and it's these recent converts whom the band play to tonight.

Not that Razorlight notice. Currently recording their second album, they are keen to show off their new wares. In The City is stretched like a piece of chewing gum that has lost its flavour, enlivened only by Johnny Borrell - singer, rhythm guitarist and self-proclaimed poet of the band - clambering over a balcony and watching from afar as the rest of the band disappear into a close approximation of the Who. It's only when Roger Daltrey joins them for a cover of Eddie Cochran's Summertime Blues that Borrell cracks a smile, preferring to stay steely-eyed and serious while attempting to justify his claim that Razorlight's work-in-progress is a "classic".

It's certainly different. The speeding, scrambled chords and energetic drums remain. Their songs are adventurous and constantly shifting: Back to the Start has a nervy rhythm that jumps from lilting reggae to edgy indie, and Fall to Pieces is a country-tinged stomp ultimately tripped up by its own cleverness.

The band are obviously still trying to work out what they're trying to accomplish, but some experiments live up to Borrell's hype. The Pilot, accompanied only by his acoustic guitar, is stark and passionate. America perfectly captures a feeling of icy isolation while tenderly embracing 1970s AOR.

But despite their dedication, Razorlight's hearts aren't in it. As Somewhere Else is enthusiastically sung by the awed crowd, it looks as if, for the band at least, the words never rang so true.
