Curiosity got the better of me on Friday evening when a night of Netflix lost out to Hannah Diamond's debut performance at The London Edition. Her track 'Pink and Blue' had me self consciously reloading into the double figures; so loathsome yet so intriguing you need at least ten second opinions to clarify that you're not going crazy by liking it. It seemed the only way to find out whether or not this love child of glitch pop and primary school lyrics is a joke was to go and witness it in person.

Filled by midnight with an army of people who'd been drinking since 6pm, the basement of The London Edition went from swanky glass box to sweat pit in no less than half hour. By the time Hannah Diamond appeared on the stage, the atmosphere was palpably ripe with unchanged clothes and spilt beer- it's a Friday night and the line between gig and club night has definitely been crossed into the latter's territory. I can't see anyone who isn't even in the slightest drunk, and it shows when Hannah Diamond appears on stage - she's received like a homecoming champion dressed like Carrie Bradshaw.

The pink North Face puffa has been replaced by a newspaper print two-piece, and I think my rum addled mind tried to make a mental note about satire, though the opening strains of' 'Pink and Blue' knocked out any semi sensible thought quick time. Two hours of A.G. Cook's high energy warm up set has made everyone go so crazy that it's like watching the moment greyhounds are let out of their cages on a racetrack- everyone wants to be involved. The fact the performance is a bit dry is almost irrelevant, because 'Pink and Blue' is a collaboration: Hannah Diamond ft. The Audience, who are shouting the lyrics at her and at each other like it's the only song anyone knows.

Whether it's stage fright or the realisation that this is no longer an internet joke, Hannah Diamond ups her game massively for her second (and final) track. Inevitably it's a rendition of 'Keri Baby' that picks her up off the spot she stayed glued to for 'Pink and Blue' and transforms her into the sashaying diva I half expected her to be. It's a performance that lasts about seven minutes and it mirrors the effect of first hearing 'Pink and Blue'- I start off skeptical and finish in a state of rapture. With thanks and a promise of new material, she's gone.

It was a debut that proved if nothing else what a bit of internet hype and a decent support slot can do for your potential popularity, though even after a weekend of deep musing I'm still no clearer as to whether or not Hannah Diamond is legit. Every time I've played Pink and Blue' to anybody it ends with fingers almost rammed into ears, but everyone wants to hear it again because there's that je n'ai sais quoi that makes it a phenomenal pop song. It's an exploitation that next time, if there is a next time, Hannah Diamond needs to bring on stage.
