We went to see Robyn, the self-styled "killingest popstar on the planet", on Thursday night. With her pale skin, straightened blonde hair and slightly troubled facial expression, she came onstage looking like an albino emo, if such a thing exists. Fortunately, she soon cracked a smile, confiding, rather sweetly, that the 1,500-strong Koko crowd was the biggest she'd played to in a while.

As she ripped into the attitude-packed pop tunes from her Robyn album, her spirits continued to soar. A bombastic version of future single 'Who's That Girl' went down particularly well, while an inspired medley of Neneh Cherry's 'Buffalo Stance' and Salt-n-Pepa's 'Push It' saluted the hip-hop roots of her hard-edged beats. Impressively, the crowd knew every word to the "selfish narcissistic psycho-freakin' bootlicking N**i creep" line from recent single 'Handle Me'. That's a lot of adjectives to remember, especially when you've had a lengthy support slot from a drag queen DJ to drink through.

The set's only sag came when Robyn crooned 'Eclipse', a pretty, low-key piano ballad that failed to hold the crowd's attention. Nevertheless, the plucky Swede soon recovered, launching into a euphoric version of 'With Every Heartbeat' that quickly became a mass sing-along. She was brave, too, retooling the flashy Max Martin pop of 'Show Me Love' into something subtle and heart-felt.

Robyn ended with an acoustic take on 'Be Mine', a tale of unrequited love that tugged at the heartstrings like the final minutes of a Disney movie. Whether she's making music for the heart or for the feet (or, as is frequently the case, for both), Robyn's sure to wrap every song in a catchy, edgy, super-modern package that sounds tremendous live. The "killingest popstar on the planet"? She's not far off, to be honest.
