“Rock ‘n’ roll was invented in Bodø about 1922,” declares Elvis Costello before kicking into “A Slow Drag With Josephine”. “Then it crept down to Trondheim,” he continues. “Then the squares in Oslo got it about 1952.” Up here, 25km inside the Arctic Circle, it actually seems possible that anything could have developed without the outside world noticing. On the tip of a finger of land between two mountain-fringed fjords, the city of Bodø doesn’t need to shout its identity. The setting is enough.

We're pleased to announce The Arts Desk is a media partner of the Denovali Swingfest London on 20 and 21 April at London's The Scala. It's a good match, as Swingfest and the Denovali label, like The Arts Desk refuse to acknowledge artificial boundaries between “high” culture, the avant-garde and grassroots electronic and club music.

“It looks like the Coconut Lounge,” remarked John Adams as he stepped up jauntily to introduce the first of two big string pieces composed 30 years apart. The folk with their drinks at the candlelit tables, though, were never allowed to sit back and let it all wash over them.

Like a streamlined sandstone-coloured satellite berthed unexpectedly in Manchester’s medieval quarter, the new addition to the country’s largest specialist music school, Chetham’s (pronounced Cheetham’s), makes a confident statement for the future. It looms seven storeys high amidst atmospheric buildings dating back as far as 600 years. 

Oxford's Message to Bears project – a fluid collective around one Jerome Alexander – is one of music's best-kept secrets. In one and a half albums in 2008-9, Alexander created a new kind of ambient music: floating, rarefied chamber pieces in which classical instruments and folky acoustic guitars are gently embellished with electronic treatments and found sound, capturing the most delicate and fleeting of moods like slivers of time frozen and held up to the light.

A music broadcaster commented after last night’s concert by the Australian Chamber Orchestra that all the hype, all the talk about the surf-obsessed, free-spirited leader Richard Tognetti, had left her half expecting them to surf onto the stage of the Queen Elizabeth Hall. As they walked on however (decorously, and rather more smartly dressed than most English groups) we were reminded that there’s nothing gimmicky about this ensemble.

Brahms composed trios throughout his life - these well-loved pieces contrast with the much rarer works of Hans Gal and the oboist Heinz Holliger, here exposed in his parallel career as a composer.

According to Classic FM’s managing director Darren Henley there are many people who find the term “chamber music” offputting, if not downright intimidating. Perhaps the best explanation of the genre comes from a musicologist who has termed it “the music of friends”. It’s a lovely description and one that, for the very best ensembles, can extend beyond the confines of quartets or duos to even the largest of symphony orchestras.

The Father, the Son and the Holy Ghost materialised yesterday. And I'm not talking about the transcendental appearance of the Holy Trinity of News International. I'm talking Proms. Last night's two saw a geriatric performance of the Brahms double, a brand spanking new way through an old Rite and a transfiguringly spectral invocation of Schubert's Quintet.

Getting to Mull is an improbably romantic journey to classical music-making. One can easily understand why Mendelssohn was so affected by his experiences in Scotland – and Mull. On the three-hour train journey from Glasgow one sheds the habits of everyday life: the train winds through thickets of Forestry Commission plantations, which suddenly open out into wild panoramas of mountains and lochs, or a dramatic ruined castle against the skyline.
