Robyn's website makes the contentious claim that the Swedish singer is the "most killingest pop star on the planet", which will be news to, say, Kylie Minogue and Girls Aloud. At the moment, though, Robyn might be the coolingest. This one-time teen star - who fell out with her 1990s label over artistic direction, a show of attitude nobody expected of the Scandinavian Britney - has been tipped all year as an interesting fusion of pop frothiness and indie self-determination. Her August No 1 single, With Every Heartbeat, justified much of the hype.

Her Scala show niftily ties those pop and indie bits together with the help of a throbbing techno soundtrack that apparently feeds straight into her veins. Her dancing is more than just euphoric; there's something primal about the shuddering and twisting that starts each time her band cranks into a new tune. They didn't teach her that in pop-star school; this is a girl who genuinely feels the music. But her stint of teen stardom did instil a knowledge of how to professionally work a crowd - she blows kisses, strikes modelling poses and flirtatiously strokes her leather miniskirt. As you would expect, the audience are deeply moved. But, actually, the effect is remarkably uncontrived. More than anything, Robyn comes across as someone who can't believe she gets paid for having so much fun.

She's vocally proficient (and while we're at it, her all-Swedish band are wizards at couching her girlish voice in futuristic electronic snaps and crackles), but her ability to hit the striking high notes on Crash and Burn Girl is only a fraction of her appeal. What distinguishes Robyn is her way of pouring herself into the songs with the emotional kapow of a blues singer. "I think I do this one better than Beverley Knight," she says, entirely truthfully, of Keep This Fire Burning.

The songs do sound great. It's all about attitude: in Handle Me, she spits the line, "You selfish, narcissistic, psycho-freaking, boot-licking Nazi creep" and sounds genuinely enraged (and so do the fans, who bawl every tongue-twisting syllable back at her), while she's convincingly belligerent as a rapper on Konichiwa Bitches. The pure pop of With Every Heartbeat and her 1998 teenybopper hit Show Me Love is simply fierce. Robyn may not be the most killingest, but she's more killinger than almost anyone else right now.
