Sasha was the original superstar DJ: a thumping, almighty force of nature who changed the face of UK dance music when he emerged from the late ‘80s Welsh underground like a coiled spring.

He graced the cover of Mixmag under hyperbolic headlines calling him “the first DJ pin-up” and asking if he might be the “son of god,” before going on to prove both of those right. To put it lightly, the hype was real.

John Digweed, his co-conspirator in Saturday night’s enormous show at SWG3’s Galvanizers space, has an intertwining story and similar pedigree.

After the two met at legendary Mansfield club Renaissance, during the peak of the “big club” era, they set about becoming the most innovative electronic duo of the time.

Pushing a progressive house style that quickly became their own, they took the mid ‘90s by storm with a hard-partying lifestyle that made them legends of the scene.

This weekend sees the duo play their first Scottish gig in 10 years: a wait that should ensure a feverish atmosphere among the notoriously keen Glaswegian crowd.

“I’m really excited about playing a big club in Scotland again with John,” said Sasha ahead of Saturday’s show. “It’s been a long time.

"There’s just an energy in the Scottish crowd that’s really amazing… There’s something magical about it.

"They’re into the music, they’re educated, they’re passionate about the music. It’s always cracking – it’s one of my favourite places to come and play.”

The Welshman was flying solo at the Sub Club last time he was in town. “Just such a brilliant place to play” is how he describes the Jamaica Street sweatbox.

“I can’t believe it took me so many years to get there and have my first show there, but there are certain clubs where you walk into the booth and you’re immediately at home and comfortable - and the crowd’s right in your face and loving every moment of it.

“You can really dig into the corners of your record box and find some really weird and wonderful new music to play and test things out, and the crowd are with you.”

For this weekend’s show, the venue is considerably larger and the two old friends are side-by-side. Does it make any difference for a veteran DJ who knows the game inside out?

“I think in a bigger venue, the energy of the music is going to be a bit higher - John and I obviously feed off each other when we’re playing and we’ll feed off that amazing Scottish crowd that is usually bang up for it.

"It’ll definitely be a different kind of show, but I’m really excited.”

Just a few years ago, only one Glaswegian venue would have been the setting for a show of this scale. But if there has been a positive to take from the closure of The Arches, it’s in the way that new venues have sprung up and others have adapted to fill the void.

The Welshman still has fond memories of the fabled Midland Street superclub, though. “I remember I played in the Arches back in the day – it was fantastic,” he said.

“They would open each arch up one by one – so they’d let the first arch fill up, then the second.

“I was getting set up in the third arch, looking out at this empty room.

"I go down on the floor and turn my back to pick out my first record, and by the time I’m standing back up again with a record in my hand, there’s this wall of crazy Scottish ravers running towards me.

“It was a bit like that scene out of Braveheart! Of course, that first record had to be a belter…”

After so long in the game, it’s “approaching music a different way” that keeps Sasha going.

“I just had a couple of weekends off,” he says, “then amazing gigs in Montreal and New York - 95 percent brand new music I played out.

"It just felt amazing to completely change my set from where it was at a month before.

“And listening to the new music that I get sent all the time for my DJ sets is so inspiring. That’s always the main thing that gives you the hunger to want to go out and play.”
