La Flash: second date at UMI for Brussels’ gay friendly Sunday

Brussels has never liked gloomy Sunday nights. For years, La Flash has kept the opposite promise: a gay friendly night, open and festive, where everyone dances. And this autumn, that promise simply continues in a new setting.

New date, new experience

The party’s historic home, the You Night Club (rue Duquesnoy 18), is going into renovation. Rather than interrupting the ritual, the team is moving the night just a hundred metres away, to UMI, rue du Marché aux Fromages 10 / Kaasmarkt 10, 1000 Brussels. In other words: same neighbourhood, same crowd, same habits — a few extra steps from the Grand-Place or Central Station.

The line-up announces Flash @ UMI on Sunday 13 September 2026, doors at 11pm. After a successful first edition at the new venue, this is already the second date of a series the team intends to run every Sunday while the You is under construction.

The new playground

For its new home, La Flash promises a full setup, designed for dancing deep into the night:

• XXL sound system
• 2 rooms: Mainroom & The Studio
• Free toilets
• 1 safe & chill room
• Cloakroom and key lockers
• Smoking room
• Safe & secure space

Tickets: first come, first served

Tickets are on sale on Shotgun, in limited availability — maximum 5 tickets per person. And as the team warns: there will be no guest list. First come, first served.

Why UMI fits the Flash spirit so well

UMI describes itself as a venue halfway between a cultural centre and a club, with a programme of local and international DJs and artists, and a clear ambition: offering a safe space for music and art lovers. On paper and on the dancefloor, the match makes sense.
