The armies of industry stylists employed to make squeaky stage-school brats resemble rock groups would have their work cut out to make anybody look like Kasabian. The Leicester band could have ridden into town on one of Dennis Hopper's motorcycles after a weekend at the Altamont festival.

Their hair hangs sweatily over their eyes, their shirts look unwashed and suggest the band's excitement at their music comes much higher on their list of priorities than shampoo and toothpaste.

You might not wish to stand too close, but a Kasabian gig is like a party thrown by rock's last gang in town where anyone is invited. At various points in an exhilarating hour, vocalist Tom Meighan dedicates proceedings to Leicester City, Leeds United, "all the rock'n'rollers" and "the mushroom people."

Similarly, their music blasts off in all directions, from Primal Scream's Swastika Eyes urban electronic period to the lush pastures of English psychedelic whimsy, all with the musical energy of a size nine Doc Marten boot following up the rear.

Stocky and eight o'clock shadowed, Meighan could have just stepped from the set of Football Factory, at one point focusing his fervour into a spontaneous - almost triumphant - cry: "Bastards!" From almost any other frontman this side of Liam Gallagher, this would be ridiculous but, Meighan has a twinkle in his eye that suggests more than bad boy charm. His band have the songs, from the enormous electro chant of Processed Beats to the adrenaline rush of betrayal anthem Reason is Treason.

When they unleash recent hit Club Foot, there's an undeniable tingle-down-the-spine factor as a member of the audience is hurled onstage and guitarist Serge Pizzorno's head ends up tangled in the lightning rig. The rest of pop is advised to batten down the hatches.
