Hometown: Stockholm and Sydney.
The lineup: Elektra and Miranda Kilbey (vocals).
The background: They look fabulous and sound dolorous. What a combination. Elektra and Miranda Kilbey are two sisters, barely out of school, who grew up flitting between Australia and Sweden and now work as a duo called Saint Lou Lou. They've got the flaxen hair and cheekbones of Mariel and Margaux Hemingway in 1978 and they sound like a depressed tATu. Their frequent peregrinations from north to south, cold and dark to sunny and bright, apparently impacted deeply on their psyches. We're no shrinks, but we do recognise the delicate sound of thunderous yearning when we hear it, and this pair obviously spent their formative years in a near-permanent state of longing for the Other Place. "When you're constantly travelling back and forth between the opposite ends of the world, you can end up feeling like you're stuck somewhere in between," they have said, in an attempt to explain the aching sense of displacement that informs their songs.
They're pop songs, not indie or electronic ones, even though you can see the alternative crowd digging them and detect elements of the latter creeping into their construction, which takes place in Stockholm with their co-writers Addeboy Vs Cliff – who produced their imminent debut single Maybe You – and Patrick Berger, who is a retired Czech footballer as well as sometime knob-twiddler for Robyn. Oh, all right, they're different Patrick Bergers. Just trying to lighten the mood, which is so deliciously sad you can taste it. In fact, super-chic French label Kitsuné liked the flavour straight away, signing them as soon as they heard the demo of Maybe You. Now the girls are planning to move to London to finish their debut album, due in 2013.
Let's just hope they don't get too happy while they're here because, let's face it, we all know what a crazy fun town the capital is right now. Even we wouldn't sanction mental torment just for our personal delight; we are simply cautiously advising Elektra and Miranda, if they'll forgive our informality, to retain that special quality of misery that serves their music so well. As commercial pop goes, Maybe You is less fizzy than forlorn, and the words are tremendous, existentialist angst-poetry for teens on Twitter. Miraculously, it's no one-off. We have been privy (we always lapse into Shakespearean when we're excited) to two further tracks, demos that prove even without the finishing studio touches these tunes work. Julian is a poignant paean to – who? Mr Temple? That's sick. Lennon? Don't be ridiculous. Perhaps it's Casablancas. "Once we get across the border – oh, Julian – I'll … mend … your … heart," they coo. It's all in the intonation. "You know I'll keep your secret." Welcome back to pop, mouth-watering mystery. Skylights builds to a peak of epic sorrow and is their third deathlessly pretty song. Three! That is more than the entire back catalogues of Manic Street Preachers, Libertines and Coldplay put together. We would hold a street party to celebrate but, like we said, we don't want to ruin the atmosphere.
The buzz: "It's so wistfully sad that you almost feel pangs of guilt for enjoying it. Almost" – Scandipop.
The truth: They're the best Aussie-Scandinavian pop duo in the world … ever!
Most likely to: Keep their exuberance in check.
Least likely to: Play for the Czech Republic.
What to buy: Maybe You is released on 27 August by Kitsuné.
File next to: Amanda Mair, tATu., Dollar, Rosanna.
Friday's new band: The Other Tribe.
