The word on the street is that Biffy Clyro are set to leap towards rock's stratosphere this summer. Album number four has seen critics run out of superlatives in a bid to herald Scot-rock's kings in waiting.

It's about time. Team Biffy - crammed in a sweaty mass against the barrier - was unswayed in its loyalty. And, with a top 20 single tickling the chart and a string of big festival slots in the diary, things are looking up. First up on the bill was former Million Dead frontman turned Bragg-esque strummer Frank Turner - a man with the kind of carefree attitude which makes you want to learn guitar and set off a never-ending globetrot.

Newcastle's Your Code Name is Milo, were next - their brand of raucous pop paving the way for Biffy Clyro to win over the crowd. And it didn't take long. Oldies Glitter and Trauma, Justboy and Questions and Answers were rolled out and welcomed with a Wembley roar.

The crowd may have been scant, but the passion could not have been more overwhelming if Elvis had turned up for an impromptu turn. The new tracks soared, Saturday Superhouse proving a rollicking gem. Biffy's time has come. That it has taken so long is criminal. They are one of Britain's best bands - and hopefully, soon, one of its best loved.
