Kaleidoscopic in the studio and a force majeure on stage, it’s no surprise that Niki & The Dove, Malin Dahlstr鰉 (voice, songs) and Gustaf Karl鰂 (keyboards, songs) met while writing a wide range of music for the theatre. But they’re definitely, and boldly pro-pop: simultaneously simple and complex but ultimately devastating pop music.

At the same time, N&D’s electronics and beats forge a pro-dance sound, but with a span from tribal to synth-pop to R&B, it’s as much a quest and a riddle to work out exactly what the pair are – which is how it should be. “In our heart, we are a soul band, not even an electronic band,” says Malin.

Both descriptions stand from the very first moments of their debut album, as the opening track “Tomorrow” unfolds a subtle pulse with pan-Pacific textures underneath Malin’s aching vocal that collectively rise to a series of euphoric peaks as vocal overdubs ramp up the feeling of a tribal ceremony. This was also the case with DJ, Ease My Mind, the duo’s debut single released in February 2010 (revamped here as the album finale). Malin’s vocal had the urgency and vulnerability of epic ‘60s girl-group pop (The Shangri La’s, say) fused to their unique version of the joyful release of the dancefloor. Time and again, the album follows the same blueprint of intent – a blend of tenderness, explosion, hypnosis and exhilaration - but never the same routine.

In the same way as Malin and Gustaf won’t use comparisons to describe their sound, they don’t feel it necessary to discuss what music has shaped their sound. In any case, Malin says, it’s not even other music that fires their imagination. “We are children of our time and of everything we have listened to all our lives. But if anything comes through our music, it’s only sub-consciously. Our influences are other art forms; a book, a painting or a poem. Or it could be the environment.”

So they became Niki & The, releasing their single on UK indie Moshi Moshi in autumn 2010. Between more recording (again with Elof, who Gustaf calls their, “critical third eye; he helps us look with a different view”), they began to play shows. Live, Niki & The Dove have a permanent live drummer, Magnus B鰍vist, with Kalle Perlskog sometimes doubling up, though when they get the chance, there are three drummers, a bassist and two dancers flanking Malin’s exuberant presence, which brings the tracks’ instinctive rhythms even more to life

Their second single “The Fox” was released in May 2011 on the legendary US label Sub-Pop, backed by “Gentle Roar” and a live version of “Somebody,” one of their most delirious pop creations. The duo then signed to Mercury for the UK and Europe, which in October 2011 released a seven-track EP The Drummer, led by its title track and also including “Last Night”, “Mother Protect” and “Manon”. All album versions of previously released tracks are remixed and revamped, while “Under The Bridges” appears here in an abridged version, shorn of its thunderous instrumental coda.

With 11 songs lined up together, forthcoming album ‘Instinct’ is an exhilarating experience, and once you’ve assimilated the lyrics (all written by Malin), like stepping into a piece of art. Take “The Drummer”. While the EP was a deliciously ambitious suite about the desert, the title track is more a story, “about a wrestle at night, in a no man’s land, where everything is uncertain,” says Malin. “It's about the inevitable question of if you're choosing the right direction in your life or not.”

Malin typically hesitates to explain her words, but will concede some guidelines. The album’s gentlest, and arguably more hallucinatory, moment, “Manon” taps what she calls the, “raging energy,” of the Arab Spring, “but to personalise it by turning revolution into a young girl.” “Under The Bridges” (“It takes me back/to the night we danced/under the bridges”) taps nostalgic memories of teenage-hood, while “The Fox” goes even further back, alluding to a children’s story used as therapy for curing insomnia but in this context, it’s a gateway to, “climb and to get a new perspective, to break free, as an adult.”

Fear also coats “Gentle Roar”, addressing Malin’s former phobia of the subway that she solved by sampling the kind of sound that had once scared her - “then suddenly the sound was beautiful and otherworldly. And then I sat down and started to write the lyric.”

In light of the BBC Sound Of 2012 poll, is expectation very much calling on Niki & The Dove? Not in their minds. “It’s wonderful, an extremely big honour, and also unreal,” Gustaf concludes. “But we just make the music that we want to, and never compromise, so no pressure. It’s not like we can change anything anyway. Not yet anyway!”
