Introducing the fifth number in this evening’s set, Erin Birgy speaks to the audience for the first time. “This is our last song, thank you,” she says. Thoughts of early Jesus and Mary Chain shows instantly surface. Is this going to be a 20-minute wonder? A five-song digest of where Birgy – who records and writes as Mega Bog – is now, playing her first UK dates since the release of her seventh album The End of Everything? Is it the end of the show?

I first saw Erol Josue on stage in Essaouria, Morocco, during the Gnawa Festival of 2011, when he fronted Jazz-Racine Haiti. The Haitian-born voudou priest turned R&B singer struck me as one of the most flamboyant frontmen ever to hit a stage.

For someone predominantly poised at her kit, the mononymous music producer’s return is surprisingly devoid of live drums. Daughter of Leftfield cofounder Neil Barnes, Georgia has made a name for herself as the drummer for artists such as Kwes and Kae Tempest. Her 2019 release Seeking Thrills was “a hymn to British hedonism” with a hefty slice of Robyn-esque pop panache. Last year saw Georgia embrace these stadium-sized singalongs as tour support for LA sister trio Haim.

The broken beat movement, centred on West London around the turn of the millennium, wasn’t super press friendly. Its complex rhythms were eclipsed in the populism stakes by its close cousin UK garage, and serious commentators didn’t really know what to do with a broadly working class, multicultural scene that was aspirational and privileged virtuosic production and musicianship. Indeed there was a distinct inverted snobbery in the refusal refusal to treat it with the respect afforded other electronic music which fit into a scholarly vs “street” dichotomy.

There are whole books to be written – indeed, hopefully being written – on how hip hop has interacted with dance music culture in North America over the past decade plus. From the overblown mania of rap megastars jumping on David Guetta tracks in the heat of the EDM explosion at the start of the 2010s, to the far more sophisticated fusions done brilliantly by Beyoncé and slightly less so by Drake on big albums last year, it’s created some of the most ubiquitous sounds globally.

“It all started with a June 7, 1976 article in New York magazine about Queens, New York working-class young adults who flocked to a local disco in platform shoes and outlandish clothes to perform organized dances. [Bee Gees manager] Stigwood read Tribal Rites of Saturday Night, and immediately bought the rights from the author, seminal rock critic Nik Cohn.”

Brit alt-indie outfit Django Django refuse easy categorisation and, as a result, during a decade-plus career, have never quite found their place with the wider public. Critical acclaim has come their way, and those who’ve kept an ear open know their catalogue contains gems (“First Light”, “Hail Bop” and “In Your Beat” spring to mind) as well as great remixes.

Of all the Scottish bands to be name dropped at a Chvrches gig, the Bay City Rollers would be far down the list. Thankfully singer Lauren Mayberry was only citing the 70s group in reference to her tartan outfit, and not a surprise cover of “Shang-A-Lang”, but the Glasgow trio do share another similarity, in that they’ve proved to have considerable staying power in the pop world.

There’s been a good deal of discussion on “the socials” about how much Janelle Monáe’s sexy image is a new thing or a big deal.

Casual viewers, still stuck on the suit-wearing image with which she crashed into public consciousness in 2010, have acted shocked at her going almost or completely unclad in recent videos and shoots. In turn fans have pointed out the obvious – that her outré sense of fashion and costumery has manifested in many ways over the years, including in plenty of flesh-baring. 

In one sense you know what you’re going to bet with Róisín Murphy. Disco beats, a lot of bright colours, costume changes, goofing about, kick-arse vocals, and hats – lots and lots of hats. And yes, all that was present and correct at the Royal Albert Hall. But in another way, any given show is alien territory.
