You can't say they haven't made the effort. All the stops seem to have been pulled out to ensure the show makes an impact. The surround-sound speaker system blasts out from every angle. An array of screens flicker with specially commissioned films for each song. And somewhere amid the melée lurk the Super Furry Animals - a band driven by a steadfast refusal to do anything by halves.

A cynic might suggest this multimedia extravagance adds visual pizzazz to a group who have never been captivating to look at: the Furries aren't blessed with a Damon Albarn as poster-boy, and rarely engage in much onstage movement. But that's not to say there's any need to compensate for shortfalls in the music. Over five albums the Welsh five-piece have, unlike most modern British guitar bands, managed to successfully and consistently blend experimentation with tunefulness. It's clear from the crowd's ecstatic reaction to old favourites such as Demons and Play It Cool that the Super Furry Animals have the knack of crafting infectious, melodic anthems. Yet this show demonstrates how vital innovation is to their success.

Look at No Sympathy, from new album Rings Around the World. As it won't be released until next week, few can have heard the song before. But they seem to like what they hear, nodding their heads as Gruff Rhys sings a brooding, anti-capital punishment invective. Then, unexpectedly, the tension is broken: a crazed techno beat begins to pulsate, and the crowd goes wild. You can't imagine Coldplay ending one of their acoustic numbers like that.

In a way, going against the grain is what we've come to expect from the Furries. This is the band, after all, whose fourth album was recorded in Welsh, and who made their mark some years back by turning up to music festivals in a tank. Yet in a British guitar scene dominated by straight-forward, down-the-line, dues-paying rock'n'roll, it's hard to think of another band who could turn their hands to salsa, country, punk and electronica with such effortless skill.

That's not to say their experiments always work. Closing with a new instrumental track, [A] Touch Sensitive, risks alienating fans eager to go out on a crowd-pleaser; extending it over a quarter of an hour seems wilfully arrogant. It's to the Super Furry Animals' credit that they take the audience with them, as the song's pounding rhythms and twin bass guitar assault tear through the speakers to rapturous cheers.

This is a band prepared to take risks but grounded in melody and good humour. In an increasingly dull indie scene, Super Furry Animals continue to shine.
