On the Jutland coast, Aarhus is Denmark’s second largest city after capital Copenhagen. Its attractive continental atmosphere is amplified by the presence of this week’s temporary population, which includes visitors from Britain, Estonia, France, Germany, Luxembourg, the US and the other Nordic countries. They’re here for SPOT, Denmark’s annual festival showcasing homegrown music. It’s a good moment as electro-popper Oh Land is making significant waves in the States. Bands like Efterklang, The Ravonettes and the seminal Mew are embedded in the international musical landscape.

The video for W’s opening cut “Doorway” is unforgettable. Janine Rostron – who is Planningtorock – is seen face on. The music is tense, yet sepulchral. The voice is treated, neither male nor female. With her prosthetic nose, she looks alien but not cutely so. It’s disturbing, a bad-dream version of what Cindy Sherman might film to soundtrack the song.

As her black robe swirled around a black leotard, Lykke Li became the anti-Stevie Nicks. Instead of conjuring the mellow California feeling, she sang “sadness is a blessing”. Yet this Swede’s pop is as uplifting, as transporting as any good vibe merchant. More so. Last night’s show transfixed with its Bo Diddley beats, gospel choruses and wheezy garage rock organ. Rather than being a retro futurist, Lykke Li takes from the past and recasts it to fit her vision of what affecting pop ought to be.

Halfway through last night’s show, as songs segued and smooshed into each other, it became clear that Robyn has perfected a high-concept pop that’s impossible to place geographically. She might be Swedish, but bloopy Chicago house, Euro electro and synthetic Japanese new wave are in the mix. A human blender, she’s at a peak – visibly fizzing.

If you’ve seen Tomas Alfredson’s remarkable Swedish adaptation of John Alfrede Lindqvist’s vampire novel Let the Right One In, then this US remake by Matt Reeves is far from required viewing. He shadows the original so closely, you’ll never be surprised or scared. But like a loving cover version of a favourite hit, there are pleasures in the riffs he plays.

Oslo’s annual by:Larm festival celebrates Nordic music. Over the three days, just under 180 acts play Norway's capital: 142 are Norwegian, 15 are Swedish, with single figures each for Iceland, Denmark, Finland and even Greenland. Time presses, and hard choices have to be made about what to see. This year, by:Larm also hosted the inaugural Nordic Music Prize, awarded to Iceland’s Jõnsi, for his recent album Go. Overjoyed, but overwhelmed, in reaction he said little more than, “Thank you so much, I’m really bad at this.”

“Don’t pull your pants before I go down… Like the shotgun, I need an outcome, I'm your prostitute, you gonna get some”. The lyrics of “Get Some”, the first single from globetrotting Swedish popster Lykke Li’s second album, are unforgettable. The album itself, Wounded Rhymes, is pretty unforgettable too.

Forty-five years ago today, Nancy Sinatra’s risqué “These Boots Are Made For Walking” entered the British charts, beginning its rise to Number One. This country-slanted ode to sex and domination, sung by Frank’s daughter, hasn’t had its impact blunted by repeated exposure on nostalgia radio.

There’s something going on in the North. Iceland’s Hjaltalín incorporate a disco sensibility and Sweden’s Concretes draw from the same well on their new album WYWH. Although this is probably not the future direction of Nordic music, it’s now an important part of it, showcases a reinvented Concretes and, judging by last night’s show, they might as well be a new band. Although still glacial – you could never imagine them breaking a sweat on stage – this show drew a curtain on their past.

By the standards of contemporary horror movies, Let Me In has several things going for it. It isn't about somebody being tortured to death, its leading characters aren't played by the usual vapid twentysomething actors pretending to be high-school students, and, by and large, it eschews some of the more tedious horror fads of our time, such as herky-jerky editing, or big "Boo!" musical cues designed to make you jump.
