When Gunnersbury Park fell away just months before its planned return, moved into — and, in the process, let something truly unique unfurl.
Pulling off a 36-hour party takes a certain amount of sheer graft at the best of times. Doing it after months of planning have been thrown into question is another matter entirely. For Waterworks, the move to The Cause became a reflection of the determination needed to keep underground music alive and evolving, particularly as the infrastructure required to support independent scenes becomes harder to secure.
The East London venue has built its reputation on doing things its own way, with its motto, ‘getting away with it since 2019’, becoming something of a calling card. For a festival built around the spirit of London’s underground, it feels like an oddly fitting place to land. Five years at Gunnersbury Park had given Waterworks the experience to make 2026 its most ambitious edition yet. The plan was a first two-day festival, with 83 sets, shows and B2Bs spread across five stages. Then, in May, planning permission fell through, leaving the organisers just months to find another way forward.
That way forward became : 36 hours at The Cause on the original September 12–13 dates. The landscape had changed, but so could the festival. Freed from the need to recreate Gunnersbury, Waterworks leaned into the character of its new surroundings, turning rooms, terraces and industrial spaces into something distinctively its own. On paper, the move could have felt like a compromise. In reality, it revealed something essential about Waterworks: its identity has never really depended on grass, scale or conventional festival infrastructure. It depends on the music, the people around it and a willingness to let the environment shape the experience.
We speak after the festival with , co-founder of Waterworks: “When we first got the news that Waterworks 2026 couldn’t go ahead at the park, we were gutted. Our team, our artists, our production partners and all the amazing crews that work on the show had already put so much time and love into the festival. We all knew there was no way we could let people down, so Waterworks Extended was born.”As was popularised by the late : “Fail We May, Sail We Must.”
“To our knowledge, there has never been a 36-hour rave of this scale in London, so it took a lot of hard work and faith and there really was no path to follow. We’re extremely proud of what we managed to deliver against the odds – watching thousands dance together over the seven concrete dancefloors at The Cause made it all worthwhile. Big ups to everyone who helped keep the dream alive!”
The Cause is a very different proposition to Gunnersbury Park. Rather than sprawling across an open green space, its various rooms, terraces and architectural quirks create a more fragmented, club-like experience. But that becomes the attraction. What might initially look like a limitation instead gives Waterworks the opportunity to lean harder into the underground club culture it has always championed.
And by the time the weekend is properly underway, the distinction between festival and club starts to feel largely irrelevant. The programming does much of the heavy lifting. Rather than attempting to recreate the scale of the original plan, Waterworks Extended embraces longer sets and a more fluid sense of movement. Across the weekend, , , and others keep the music moving between rooms without ever letting the energy settle.
At one point, Bradley Zero is playing in the Gallery, going B2B with for a four-hour set. Zero has spoken fondly about his relationship with Waterworks, recalling his previous appearance alongside Moxie, while Alkan was one of the artists he discovered after moving to London and finding his way into techno and house. It’s a pairing that makes sense within Waterworks’ own approach to bringing different strands of music together. Alkan’s genre-spanning career makes the pairing feel right at home within Waterworks.
Inside the Gallery, that history feels less like a footnote and more like something being played out in real time. The room fills beautifully as the set develops, with ravers seemingly engaged in their own minor battle over the two most valuable commodities in the building: the speakers and the air conditioning. People push towards the sound, while others try to find the coolest possible pocket of the room.
The set doesn’t rush towards gratification. Chugging tracks gradually establish the atmosphere before giving way to more recognisable crowd-pleasers, each one carrying subtle acid twinges that keep the energy from becoming too predictable. Then comes a rework of the Stone Roses’ ‘I Wanna Be Adored’, its familiar pull transformed for the dancefloor, sending the room into full flight. It’s a moment where the reaction feels earned rather than forced.
The Cause’s installations and industrial architecture become part of the experience too, with work from artists including and , alongside the visual work of and others. The venue has its own visual language, and rather than covering it up, Waterworks allows the festival to sit within it.
Moxie b2b bring an effervescent energy to the terrace, perfectly suited to summer’s final stretch. Moxie, real name Alice Moxom, has spent two decades building a reputation as one of London’s most instinctive DJs and radio voices, moving between deep house, Detroit techno, disco and leftfield club music. Her long-running NTS residency and On Loop label have made her a central figure in the city’s wider dance music ecosystem.
Beside her, Parisian DJ and producer Dyed Soundorom brings a different kind of underground pedigree. His route into dance music began in Paris nightlife before developing into a career that has taken him through some of the world’s most respected clubs, from Panorama Bar and Fabric to Circoloco at DC10. Together, they catch that fleeting point where the afternoon starts to feel endless, the terrace at full swell with the Warehouse, Workshop and Hot House all within reach — every doorway offering a different route into the night.
The terrace itself is a striking part of the experience. Set beneath a huge concrete building, the stage sits in a courtyard surrounded by layers of balconies, walkways and weathered industrial architecture. Ravers pack the space below while others lean over the railings above, looking down onto the crowd. Plants spill over the edges, lighting rigs cut across the space and a huge screen sits above the stage, creating a setting that feels part nightclub, part brutalist courtyard.
It’s a world away from the open expanse of Gunnersbury, but there is something compelling about the way the crowd occupies every available level. ‘Make The World Go Round – Deep Dish Radio Edit’ comes through at one point, perfectly suited to the housey set and one final kiss of summer sun.
, real name Lea Lang, is equally taken with the space. Playing the Terrace alongside , the Cologne-based DJ says she found a “really nice groove” throughout their set, while her first Waterworks experience offered a chance to reconnect with artists and friends at the end of the festival season. “The Cause was very busy throughout the day and I thought it was a good alternative to Gunnersbury Park as the club provides very different rooms/stages,” she says.
For Lang, that diversity is part of what makes Waterworks important: “Festivals like Waterworks are really important for the wider scene, especially with such diverse programming and the way they bring so many artists and crowds together.” She still hopes the festival can eventually return to Gunnersbury Park, but her comments capture the success of the alternative Waterworks created at The Cause.
Later, as daylight fades, the mood shifts with it. What works during the afternoon changes once the sun disappears. The terrace becomes a different proposition, while the indoor rooms take on greater weight. Waterworks Extended’s “outdoor by day, indoor by night” promise begins to make practical sense rather than reading as promotional shorthand.
By the evening, Eris Drew is in the Warehouse. A Chicago DJ and producer who has been mixing records since 1994, Drew has spent decades developing a highly instinctive approach to rave, vinyl and improvisation, with her concept of the “Motherbeat” rooted in the idea of music as a force capable of transforming bodies and communities. It makes Drew a natural fit for the room.
Above the crowd, and ‘s striking polycarbonate and mirrored chandelier installation hangs in the darkness, incorporating lasers and custom visuals. The circular structure slowly rotates, each mirrored section switching direction and catching the light before pouring it into different parts of the room. Red light washes across the crowd, then shifts again with the movement of the structure, making the whole space feel alive.
Drew seems completely at home in the theatre of it all, wielding chaos in the palm of her hand. Rigged speakers are gradually dragged closer to her as the set gathers momentum, while Drew slaps vinyl onto the decks one record at a time, somehow making each move feel completely instinctive. There are nods to the familiar too — Nightcrawlers’ ‘Push The Feeling On’ gets a huge reaction — but the set is packed with deep cuts, left turns and stranger selections that keep the crowd guessing. By the end, she’s sent the room into a frantic dervish, completely losing its mind beneath the rotating installation. It’s almost silly just how talented Drew is — watching her work through record after record, knowing exactly when to twist the energy and when to let it run wild.
One of the advantages of The Cause is how easy it is to move between those moments. You can drift from the terrace into a warehouse, upstairs and back outside again, with each room offering a completely different temperature. That feels particularly aligned with Waterworks’ own approach to its timetable. In the festival’s guidance to attendees, it describes Waterworks Extended as being “designed for musical discovery”, encouraging people to spend time with “new artists in new spaces” and to “try something new”. The timetable is presented less as a checklist of headliners and more as an invitation to explore.
It’s an ethos that makes more sense once you are inside The Cause. The architecture encourages movement, and the programming rewards it. The result is a festival experience that feels closer to London club culture in its most communal form; an approach that becomes even more apparent on Sunday, when the festival shifts towards the crews and platforms that have shaped the UK’s underground.
The takeover is one of the day’s highlights, bringing together different generations of bass music in the same space. s drum & bass vinyl set builds towards a huge moment when she drops its instantly recognisable bassline whipping the room into a frenzy. Then there’s Simon Scott b2b Beatrice M. — a particularly fitting collision of generations. Scott, founder of Sub Dub and one of the figures associated with Outlook’s long-running bass culture, goes back to back with Beatrice M., founder of Bait and a defining voice in the newer school of dubstep and dub techno.
Speaking to the Outlook organisers, they describe the takeover as “a real pleasure” to bring back to London, with the day also creating a chance to connect this year’s festival with Waterworks. When had to pull out due to illness, they say it was “a no brainer” to put together the three-way set between and as Globex Corp and , turning the replacement slot into “some techno into 160 madness.” Octo Octa’s drum & bass set had already gone down a treat at Outlook’s Olive Grove in July, making her appearance at The Cause’s Workshop feel like a natural continuation. “The crowd was so receptive to the Outlook vibe throughout the day,” they add.
Elsewhere across the Sunday programme, artists such as , , Tim Reaper and underline the depth of the programming. There is a sense of history without the day becoming a museum piece: established jungle figures sit alongside artists pushing the sound into new territory, while the Outlook takeover brings different corners of bass culture under one roof.
That breadth is what makes the Sunday programming feel important. Rather than simply booking a collection of recognisable names, Waterworks gives established crews and communities room to present their own musical worlds. , , , and each arrive with their own histories and audiences, creating a cross-section of the UK underground that feels connected without becoming homogenised.
It also mirrors what Waterworks is doing physically with The Cause. The festival has been forced to work within an existing building, and on Sunday it effectively does the same thing culturally: instead of imposing one identity across the site, it creates space for different scenes to overlap, collide and find new listeners. This is not to say the relocation is invisible. Of course it isn’t. Gunnersbury Park would have offered a different kind of scale, and there is inevitably something lost when a festival moves from an expansive outdoor site to an existing venue. But Waterworks Extended isn’t really trying to pretend otherwise.
The decision to introduce a 36-hour format and emphasise extended sets makes the change feel intentional rather than apologetic. That is what makes the whole thing work. Waterworks could have spent the weekend feeling like a festival displaced from where it was supposed to be. Instead, The Cause becomes the story. Its terraces, rooms, upper levels and strange corners provide a framework for a festival that is less about spectacle and more about immersion.
There is also a deliberate visual component to that transformation. Rather than simply dressing The Cause up to resemble an outdoor festival, Waterworks brought on board artists and visual designers to treat its seven spaces as individual environments. The Warehouse gets a polycarbonate and mirrored chandelier structure incorporating lasers and custom visuals, while the Terrace features bespoke VJ work. Elsewhere, the Workshop’s architectural and lighting concept comes from London collective badweather, using a resource-conscious approach to temporary construction, while the Hot House incorporates an IVL Photon Array.
The result is a venue that feels adapted for Waterworks rather than merely occupied by it. Most importantly, Waterworks doesn’t appear diminished by the setback. It has had to become something else. And perhaps that is the unexpected lesson of Waterworks Extended. Festivals spend enormous amounts of energy creating temporary worlds, but sometimes the most interesting thing they can do is surrender a little control. The loss of Gunnersbury Park forced Waterworks to rethink its physical identity, and The Cause gave it a different vocabulary with which to speak.
By the later hours, the question of whether this is the Waterworks people originally bought tickets for becomes beside the point. The crowd revel in the weekend offering, the rooms are shifting in character, and the music keeps pushing people to explore more of the venue. A major logistical setback became a reason to experiment with format, atmosphere and space. In the end, the detour delivered something Waterworks might never have discovered by following the original plan — a reminder that what makes Waterworks isn’t tied to any one physical setting, but to the people, music and sense of possibility that bring it to life.
