First it was staunchly mainstream student hangout The Garage, and now on Saturday it's Subculture's turn to celebrate.
The two have both enjoyed fantastic success over the years, but they couldn't have more contrasting clientele.
Subculture's crowd is… well, cultured: discerning, rapier-sharp and hungry for the finest cuts of prime house music available.
The Garage's crowd enjoy bouncing on bouncy castles to Bon Jovi.
It doesn't take a genius to work out which is the more culturally credible club.
This is why you should be down at Jamaica Street celebrating this weekend.
The Sub Club's legendary Saturday night is no stranger to huge guests, but for this double-decade party they're keeping it in the inner circle: leaving it to the residents who have kept the club ticking over for all these years.
Harri and Dom, we salute you.
The icing on the Subbie's metaphorical cake is tonight's launch of new Thursday nighter Hide, which features phenomenal Frenchman Rodriguez Jr playing live.
His shimmering, downtempo electronica is at its best on the Original Mix of Lila, a subtle and tremendously hooky tune.
l Hide with Rodriguez Jr, tonight, Sub Club, Jamaica Street, 11pm-4am, £6/8
l 20 Years of Subculture - The Residents' Party, Saturday, Sub Club, 11pm-3am, £10
The coolest Cat
WE first saw Norwegian DJ Cashmere Cat in the sweaty confines of Make Do last year, on his first round of low-key UK gigs.
He's back in the city in support of his new EP Wedding Bells, which is out on Glaswegian collective Lucky Me's label.
With attention on the young producer now moving beyond the blogosphere - helped in no small part part by an appearance on the Grand Theft Auto V soundtrack last year - now would be the perfect time to catch him in the intimate confines of Broadcast, currently a contender for coolest boozer on Sauchiehall Street.
l Cashmere Cat, tonight, Broadcast, Sauchiehall Street, 11pm-3am, £11
COUNTERFLOWS is, without any doubt, the best avant-garde and improvisational music festival happening in Glasgow this weekend. (It's the only such event).
While some of the more out-there offerings will almost certainly bear a distinct resemblance to Reeves and Mortimer's Mulligan and O'Hare and their famous cover of Phil Collins' Another Day In Paradise (a version performed using ancient, mystical instruments), there's plenty to get excited about, too.
Take, for instance, Heatsick's Extended Play, on Saturday: a four-hour live set/art installation which messes with temperature and other senses to create an overwhelming dancefloor experience quite unlike any other.
Berlin-based dance artist Heatsick will be joined onstage by a range of guests, including Glaswegian noisemakers Golden Teacher and the festival's artist in residency Joe McPhee.
Oh, and it promises "lavender, yoga mats and special drinks." Sold.
l Late Night Counterflows with Joe McPhee, tomorrow, CCA, Sauchiehall Street, 11pm-3am, free
l Heatsick's Extended Play, Saturday, The Art School, 11pm-3am, £10
