Bristol’s multi-venue electronic music & Arts festival

EN MASSE 2025 IS HERE

En Masse 2025 is back in Bristol this 9-12 October 2025: bigger, bolder, and unapologetically underground.

We’re celebrating our 5th anniversary with a 4 day music programme that merges electronic music, live performance, and collaborative art across five Bristol venues. A wave of sonic chaos.

Whether you’ve been with us before or this is your first time, we’re ready to welcome you to the fold. Let’s make this one unforgettable.
