The equipment pictured above is the Powertran 1024, one of the first digital sequencers to hit the market. According to the May 1981 issue of Electronics Today International magazine, which unveiled it to the public, the British-invented “1024 composer is a machine which will repeatedly cause a synthesiser to play a pre-determined series of notes either as short sequence or a large compositions of 1024 notes: i.e. several minutes long.” The article was headlined “Treat your synth to this sequencer/composer.”

Berlin's electronic music world has been traditionally been very white. Sometimes, as with the inward-looking minimal techno of the 2000s, it could feel painfully so. Obviously a city can't really help the nature of its demographic, but monoculture is rarely healthy for the development of living club scenes – and it certainly needn't be that way.

One of the great things about club music is that it deals with ageing in very different ways to rock – and as such can offer fantastic creative rebirths. Witness theartsdesk's recent startling Q&A with Mark Hakwins aka Marquis Hawkes, who'd been around the artistic block and back a good few times before achieving his current success. Or Sean Dickson – the singer with Scottish indie band The Soup Dragons, who went from Eighties psychedelic janglers to Nineties baggy-clothed ravers, then faded away.

This is not a standard dance music story. Marquis Hawkes is one of the club music success stories of the past couple of years – since the first release in 2012 on Glasgow's revered Dixon Avenue Basement Jams, there've been many 12" club hits on multiple connoisseurs' labels, and his album Social Housing on the Fabric club's Houndstooth label has soundtracked many people's summer this year, with the artist all the while remaining anonymous.

Detroit techno music is important. Any student of the club music of the modern age knows this. The sound that fermented among the majority black population of the decaying industrial city in the late 1970s and early 1980s, as disco's last remnants fused with the avant-garde experiments of Europeans who were first getting their hands on synthesisers and drum machines, went on to change the world. It seeded the UK's rave explosion, jungle, drum'n'bass and all the electronic experiments that came after.

Dance music has, for millions of people, become synonymous with the very worst that the human race has to offer. Preening, vain, beach-body bumholes dancing like everyone’s watching, while keeping half an eye on their camera, making sure than the framing is right, no matter that they’ve got everything else wrong.

A few beers down, in the middle of a crowd listening to music you love, you tend not to think of the latest news story as your highest priority. But Britain's relationship to Europe weighs heavy on the mind these days, and when the news of the violent attack on Jo Cox started filtering through as we danced under the Catalan sun on Thursday afternoon, it threw the nature of Sónar festival into relief.

Canadian singer/producer Jessy Lanza's records – and this one more than ever – can feel like they're mapping an alternative history, one where populist and leftfield electronic music were never separate. Two aspects dominate her sound: her crisp, clear pop vocal, and a palpable love of the sonorities of drum machines.

Denmark is casting a shadow in a way it has not done before. The international success of Copenhagen’s Lukas Graham is unprecedented. While Aqua, The Ravonettes, Efterklang and Trentemøller are amongst the great Danes who have made international waves musically, Graham has trumped them all to become a surprise world-wide bestseller with the single “7 Years”.

Hearing that both Javier de Frutos and rabbit heads appear in the new BalletBoyz bill might give you pause. A choreographer so unafraid of graphic content that he started his career with naked one-man shows, and later made a piece about the Pope so sexually explicit and offensive that he got death threats – do the rabbit heads mean we're in for some kind of furvert orgy?
