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.

We have chosen to offer the Festival Pass again this year, which allows access to all events. This pass is your all-access ticket, granting entry to 3 days of music across 4 venues including:

Thursday 9th October: Gig @ Document
Friday 10th October: Club night @ Trinity Centre
Saturday 11th October: Gig from 19:00 @ Strange Brew
Saturday 11th October: Club night from 22:00 @ The Island (Festival Pass holders only)

Our festival pass is the ONLY way to gain access to the club night on Saturday. PLUS, it’s the most affordable way to join us. Don’t sleep though, our passes have sold out before we even announced the lineup in previous years. This is your chance to lock in your spot.All events are also individually ticketed below (except Saturday night at The Island), so if you want to pick and choose, you can.

We will shortly be launching our full Community and Arts programme which runs alongside the Music programming, with most events free to attend (limited signup spots available). More details coming very soon.

Please read our Terms & Conditions via our FAQs.

**We will only sell festival passes through Headfirst, beware of ticket touts. Some tickets to our Document event are available through Skiddle, some tickets to our Trinity Centre event are available through their website. The Festival Pass does not gain you access to our Sunday evening event**
