For as long as there have been subcultures, there have been overzealous authorities trying to clamp down on them. For the original ravers, who had always flirted with illegality when throwing their era-defining open-air parties in the early ‘90s, their moment came in 1994.

Section 63 (1)(b) of that year’s Criminal Justice Act gave police the power to remove people from events that featured music “wholly or predominantly characterised by the emission of a succession of repetitive beats.” As an attempt to define an illegal rave, the wording is LOL-worthy in its simplicity – or at least it would be if it weren’t so draconian.

The law had its intended effect – it was the beginning of the end for rave culture. Police crackdowns and Britpop followed, and the movement all but disappeared eventually, save for a few diehard promoters. It seems fitting, then, that tomorrow’s enormous warehouse party at SWG3 is a celebration of those golden years.

As was the case two decades ago, local hero Mallorca Lee is at the heart of it all. As well as headlining under his Ultra-Sonic alter-ego, he’s handpicked an all-star lineup of artists who made a huge impact on the scene.

Acid house producer Adamski is chief among them. The Englishman was the auteur of one of the movement’s biggest hit, the UK number 1 Killer, which launched Seal’s music career. “The ‘live your life the way you want to be’ lyric spoke to a generation,” the vocalist told the Guardian, looking back on their 1990 mega-hit. It’s hard to argue: within weeks of its release, the duo were household names and rave was firmly embedded in the public consciousness. Things would never be the same again.

Ayrshire is well-represented, too (which is funny, really, given its reputation for having a progressive, forward-thinking cultural stance). Trevor Reilly, of Ayr’s former hardcore stronghold Hanger 13, and Joe Deacon of Saltcoats’ Metro club fly the flag for the Shire. Glowsticks at the ready, folks.

Jackmaster

Oh, jings. Jackmaster and Optimo, playing on the same night, in the same venue. How is this allowed? The two Sub Club favourites might appear completely different on the surface, with both appealing to wildly different crowds. But they share a common theme: the ability to flit between genres, periods and atmospheres seemingly on a whim, while building tension and playing with light and shade during their sets.

“He knows his job is to curate, mix, and recontextualise other people’s records, not make his own music, and he’s good at it,” Pitchfork said of the former in their review of his recent-released DJ-Kicks mix. The same goes for the veteran Glasgow duo, who are so revered and so ubiquitous around the city’s clubs that they really need no further introduction. Safe to say, this chance to see two of our best-loved institutions, back-to-back on the one night in an iconic venue, is one that should be grabbed with both hands.

• Jackmaster and Optimo, tomorrow, The Art School, 11pm – 3am, £12.50

Tiga

“Real DJing is about something that can’t be packaged or replicated: it’s about timing,” Montreal’s Tiga wrote in the Guardian recently. “It’s like stand-up comedy: you’re only as good as the connections you make and the speed with which you make them. DJing is wit.”

This wittiest of spinners has always straddled two worlds. On one hand, he’s the underground club kid – bashing out hands-in-the-air techno tunes like it’s the easiest thing in the world. On the other, he has a pop sensibility that has made him one of Canada’s biggest musical exports. The Turbo Recordings head honcho doesn’t pass through here all that often – it’s been around a year and a half since he was last in Glasgow – so get your paws on a ticket if you can.

• Tiga and Jonas Rathsman, tonight, Sub Club, 11pm – 3am, £10

Sunday Circus: The End

Sunday marks the end of an era as we say goodbye to Sunday Circus - the beloved techno institution that has been running at The Courtyard, and other venues, for nine years. “It is with a heavy heart but countless happy emotions and memories that we have decided to bring Sunday Circus to an end,” residents Tricky and Affi Koman wrote on Facebook announcing the decision, which has broken the hearts of techno fans across the West of Scotland. Their final blowout looks set to be one of the year’s most memorable parties: it features the London techno and house DJ Craig Richards, it’ll be the last time the iconic club takes place under the Courtyard’s imposing brick square. Sad times indeed.

• Sunday Circus: The End, Sunday, The Courtyard, 3pm – 11pm, £14

• Afterparty, Sunday, The Berkeley Suite, 11pm – 3am, £5
