The use of Sigur Rós’s aural drama for the soundtracks of Life on Earth, Vanilla Sky and its subsequent sound bed ubiquity has meant their music has become divorced from who they are. The enthralling Valtari emphasises that these four Icelanders are a band rather than a machine supplying lazy directors with ready made atmospherics. Even so, Valtari’s “Ekki múkk” and “Varúð” are so spectacular they’ll no doubt warm the hearts of filmmakers world wide.

For a Brit navigating Denmark’s annual showcase of home-grown music, it’s impossible to eradicate thoughts of the Danish TV seen in the UK recently. Obviously, detecting Borgen-style intrigue while wandering around is unfeasible. But something else might be more obvious. However bright the sun, the wind is cold and warmish clothing is essential. Yet no one sports a Sarah Lund jumper. It’s a reminder that TV drama isn’t a guidebook. SPOT’s cutting-edge crowd has no idea about foreign notions of what might constitute Danish.

Goods, the second album by Sweden’s Edda Maganson was one of last year’s highlights. With a playful jazz sensibility which intertwined with a quirky pop, Magnason’s approach was unusual and refreshing. Coinciding with the release of her new EP, theartsdesk premieres the video for its lead track “Jona”.

Two things are certain with music coming from the north: there will be some wonderful surprises and some of it will sound like nothing else on earth. It’s even more enticing when the two merge. Making the peculiar accessible is a uniquely Scandinavian knack. There are more than a few examples of that – the creation of new micro-genres – in this round-up of current and new releases, but some straightforward albums are equally striking. First, however, we head for the offbeat end of the spectrum.

It began with a warning. Opening the fourth Tallinn Music Week, Estonia’s President Toomas Hendrik Ilves cautioned, “In a free society, it’s risk-free. In an un-free society, it’s not risk-free. It’s not all fun.” From behind a hotel conference room lectern, he then began rolling a video of Russia’s Pussy Riot being arrested in Moscow a few days earlier. Not everyone can make their point, make their music, choose how they want to get it across.

Norway’s bouncy electropoppers Casiokids release their new single “Kaskaden” next week. They’ve chosen to premier the video on theartsdesk. Directed by their long-term collaborator Blank Blank, the fantasia takes in Kung Fu films and the Hollywood of the Eighties, mixing them with a Norwegian flavour.

Oh Land is Nanna Øland Fabricius. A proper pop star in her native Denmark, based on last night's show there’s no reason why she can’t be one here too. She’s been living in Brooklyn and the international market is clearly in her sights. The highlights from her packed gig at Heaven - "Sun of a Gun", "Wolf & I", "White Nights" and "We Turn it Up” - are sweet confections that ought to prove irresistible. Providing, that is, they’re served up correctly. But more on that later.

Although the four days of Norway’s 15th by:Larm Festival were dominated by the presentation of the second annual Nordic Music Prize, there were plenty of other distractions: a sobering tour of Norwegian black metal’s infamous sites, a talk by legendary Nigerian drummer Tony Allen, what felt like millions of shows in millions of venues, and weather confounding all expectations of what Oslo ought to be like in February.

Long winters, when most outdoor activities are off the menu, must encourage creativity. Judging by the new releases in from Scandinavia, almost-constant dark and sub sub-zero temperatures would do the music of more temperate regions some good, feeding inspiration. Whether it’s Norwegians with a yen for the spooky, irresistible accordionists and disturbing singer-songwriters from Finland, or do-it-yourself Danes, all and more are here.

It’s about the bass and the drums. The choirboy high vocals and sugary melodies catch the ear first, but they’d be so much soufflé without the room-shaking, stomach-wobbling bass throb, the Chic-style disco drumming and its tsk-tsk-tsk hi-hat shuffle. Combined, the soft and airy, the propulsive and grounded make the audience move. Not tap a toe, but actually move – dance.
