Scotland’s longest-running dance festival returns to Braehead on Saturday for a manic 11-hour session of arena-sized bangers and old school anthems. The UK trance artist Ben Nicky plays the closing set on the main stage, backed up by Dutch producer Ummet Ozcan and Colours 2017 resident Will Atkinson.

The Canadian duo DVBBS, who have been making waves recently with Drop It and their recent Steve Aoki and 2 Chainz collaboration, also feature on the main stage. There are five other stages to explore, with Hamburg producer Neelix, English veteran Darren Styles, and the right honourable George Bowie among the highlights. It goes without saying that things are going to fully kick off at this one, so be ready.

· Coloursfest, Saturday, Braehead Arena, 5pm – 4am, £49.50

Josey Rebelle

Josey Rebelle is a London DJ who locks down aerials on Rinse FM, makes crushing mixes for Resident Advisor and Discwomen, and holds a residency at Plastic People: she’s basically royalty. She plays at Numbers’ latest party at La Cheetah on Saturday, where she’ll be joining the dots between house, techno, disco, rare groove, soul and garage. She’s joined by another Numbers debutante – the Glasgow DJ Bleaker, whose synthetic soul jams have made him a firm favourite with the local crew.

Dancing in the Dark Disco

It might not be on the same scale as Optimo’s twentieth anniversary celebrations the following day, but this Springsteen-centric soiree at SWG3 on Saturday night still has a lot to offer. Kicking off early, it features the first Glaswegian performance by the all-girl Boss tribute The She Street Band, followed by a Bruce-themed dance party helmed by the Dancing in the Dark DJs. Tunes from the likes of the Stones, Prince, Bowie, The Clash, Wilson Pickett, The Ramones and James Brown can be expected, so forgive me for being more than a little excited.

On Monday and Tuesday, after the Pixies’ sold-out gigs at Kelvingrove Bandstand, head to Broadcast for a Remake Remodel aftershow. There’ll be a solid hour of Francis and the gang from 12am, and a psychedelic visual installation inspired by Salvador Dali and Luis Bunuel’s Un Chien Andalou, which itself inspired the classic tune Debaser. Be sure to use that factoid to make yourself sound super-switched-on and watch the members of the opposite sex queue up to bask in your superior wisdom.

· Dancing in the Dark Disco, Saturday, SWG3, 9pm – 2am, £16

· Remake Remodel, Monday and Tuesday, Broadcast, 11pm – 3am, £3/£5

Name a more iconic duo from Glasgow’s clubbing history than JD Twitch and JG Wilkes. I’ll wait.

Two decades on from the genesis of their cult club night Optimo (Espacio), the pair – also known as Keith McIvor and Jonnie Wilkes – have cause for celebration. They’ve spent almost 20 years at the cutting edge of the city’s music scene, and in that time they’ve established themselves as two of our most essential cultural figures. They’ve also made a name for themselves internationally, taking Optimo on tour to Berlin, Paris, New York, Tokyo and other dance music capitals around the world.

It’s really difficult to overstate just how important Optimo has become. Tens – maybe hundreds – of thousands of words have been written about it, all at pains to describe the joyous eclecticism it promotes, the wonderful egalitarianism of it all. “We could never have imagined that what started out as a small gathering of like-minded freaks on Sunday nights would flourish and endure two decades later,” said the duo. To mark that milestone, they’re throwing a one-day festival at SWG3’s new Galvaniser’s Yard on Sunday, with acts ranging from the Chicago techno and disco doyenne The Black Madonna to Glasgow art-poppers Happy Meals and experimental industrial noisemaker Nurse with Wound. Elsewhere, the Ghanaian icon King Ayisoba brings his kalogo, Londoner Ben UFO dishes out bass-driven house bangers, and Australian singer-songwriter Carla dal Forno is there to captivate with her hypnotic, dreamlike soundscapes.

The club’s motto has always been “we love your ears,” and with this lineup the affection is clear. And if the video of the seven-foot-high strobe light posted to the party’s Facebook page is anything to go by, your eyes are in for a treat too. The afterparty takes place back at the Subbie, with a super-secret special guest act appearing at midnight and, according to Optimo themselves, a “performance of a certain Optimo cult hit which well may go down like a lead balloon as it is from so far back in the mists of time that even the vocalist can barely remember the lyrics.” It’s hard to imagine a more fitting tribute to an amazing twenty years.

· Optimo 20, Sunday, The Galvaniser’s Yard at SWG3, 2pm – 11pm, £40

· Thee Optimo 20 Official Afterparty, Sunday, Sub Club, 11pm – 3am, £10/£15
