Goldfrapp's third studio album, Supernature, has caused an outbreak of mass critical hyperventilating, with the editor of NME calling it the "sexiest album around". Supernature is voluptuous, certainly - a heady brew of electro, synth-pop and disco camp. Yet this short, open-air midnight set from singer Alison Goldfrapp and partner Will Gregory hints that the duo's ultra-sleek material is short on hooks, melodies and truly meaty songs.

The diminutive Goldfrapp takes to the stage in a relatively demure Emma Peel-style black catsuit. She is as perfectly presented as her band's music, an engaging cipher for the immaculate sheen of the reclusive Gregory's techno-doodles.

Visually, they pull out all the stops. For the velvet throb of Ride a White Horse, Goldfrapp is joined stage centre by two female dancers in equine costumes who prance coquettishly over the layered beats. They return as nymphs for current single Ooh La La, which is essentially Spirit in the Sky coated in electroclash gloss.

The ingredients are all there, but what is lacking is the alchemy and indefinable magic that make for truly great pop. Goldfrapp pouts like a Trojan as she strives to project irresistible sexual allure, but even former hits Train and Strict Machine fail to provide the musical ballast to her valiant preening.

She's unhappy with the truncated nature of the set, leaving with a muttered "This is all we can fucking do, I'm afraid." You can't fault their effort, but if Goldfrapp are to become true sex gods, they will need to learn to turn a few more tricks.
