ArcTangent 2026: 13 Bands You Need to See!

Across four days, ArcTangent Festival brings together the very best in post-rock, post-metal, mathcore, blackgaze, sludge and experimental heavy music, creating countless clashes and more must-see performances than anyone could realistically fit into one weekend. Whether you’re discovering your next obsession on a smaller stage or finally witnessing a legendary act you’ve waited years to see, ArcTanGent has built its reputation on rewarding adventurous music fans.

This year’s edition feels particularly special. Farewell performances, long-awaited reunions, landmark anniversary sets and some of the most exciting new names in heavy music all collide across one of the festival’s strongest lineups to date. Narrowing over a hundred artists down to just thirteen was no easy task, but these are the bands that stand out as essential viewing. From established innovators and genre-defining pioneers to rising acts on the verge of something much bigger, these are the performances that deserve a place at the very top of your ArcTanGent schedule.

1. Svalbard

In a perfect world, we would be looking forward to Svalbard’s Arctangent 2026 appearance as nothing more than another opportunity to celebrate 15 glorious years of one of Britain’s best Blackgaze and Post Rock bands. Alas, this will be the last chance we all have to hear some of the most emotionally confronting and stylistically diverse extreme metal songs ever produced by a UK band as Svalbard prepare to call it a day. Citing both the crippling financial costs of being a touring band in 2026, and their want to go out on a creative and amicable high, let’s gather to honour the legacy of this incredible force of nature one last time.

2. Dimscûa

In 2025, the Berkshire five-piece Dimscûa released their debut album Dust Eater. An album that garnered huge critical acclaim and saw an unexpected yet totally deserved shift in their exposure. It’s not often that post-metal bands get such an across-the-board vote of approval, especially those who incorporate confrontational, atmospheric sludge and emotive, complex soundscapes. But Dimscûa are quite clearly a very special band who managed to catch lightning in a bottle in the studio and are more than capable of replicating it live, as their recent sold-out tour would suggest. This Wednesday slot feels like one that will go down in ATG folklore, don’t miss it.

3. Alcest

As the new school of Blackgaze continue to evolve and impress, this is a chance to celebrate the pioneers and architects of the genre. Alcest founding member and multi-instrumentalist Neige has quite clearly slowed down with the touring over the past few years. Along with drummer Winterhalter, they have spent decades of constant worldwide touring, whilst fitting in time to record some of the most ethereally spiritual and deeply nuanced blackened shoegaze and post-metal albums in the genre’s history. But given it’s clear that the band have decided to cut back on the live performances, this opportunity to see these legends bring their beautifully terrifying music to life should be grasped with both hands and is a can’t-miss moment for everybody.

4. Psychonaut

Without pussyfooting about it, in my opinion, Psychonaut are one of the best live bands on the planet right now. A tech-prog post-metal 3 piece who, over the past twelve years, have released five of the most complex and diverse post-metal albums to ever come out of Belgium. But it’s in the live space that this band really play their trump card. These three gentlemen are absolute masters of their instruments, and rarely do many other bands manage to weld their individual genius together on the stage better than these guys do. Expect a high-intensity schooling in the ways of technical post-metal and a performance that leaves you questioning the physics of what is instrumentally possible.

5. Møl

It feels like yesterday that Danish blackgaze sensation Møl unleashed the incredible Jord upon the world. And in the eight years that have passed, they have continued on their rocket to the moon with two more fantastic albums and a touring schedule that would put most people in an early grave. Earlier this year, Møl released Dreamcrush, an album that saw them make a huge handbrake turn and progression, with a huge expanse in their sonic delivery and lead singer Kim Song Sternkopf showcasing a range of depth which had previously been unexplored. And for many, this album will be in their end-of-year Top 1-5s and rightfully so. Møl live is a sensory overload and an emotional rollercoaster of an experience, and in this setting should be one of the sets of the weekend.

6. The Tony Danza Tapdance Extravaganza

Of all the bands I would have put money on making a comeback in 2026, The Tony Danza Tapdance Extravaganza were pretty low on my list. Not because I had no interest or investment in it happening, quite the opposite. But when you consider the time that has passed since their last release and the niche nature of this band when they were at their peak, it felt like a moment in time that had come and passed. So when ATG announced them for their 2026 lineup along with a string of UK club dates, it felt like Santa had finally gotten around to reading my letter from the early 2000s. One of the very few bands of the math-tech core era who never made it to our shores, this might actually be the set of the weekend that I am most looking forward to. If you like aggressive, metallic chaos and beatdowns that feel like Dr. Strange has knocked your soul out of your body, then you need to make this set a priority.

7. Ian

Earlier in the year, I released a feature that highlighted some of alternative music’s bands to watch out for. Amongst those bands was the East London quintet and premier noise makers, IAN. I was lucky enough to catch them live in the extremely intimate setting of the Devonshire Arms, Camden earlier in the year, and I am fairly certain that my hearing has only fully recovered from that show very recently. IAN play a loud, heavy and intense form of post-metal that will pull on your heartstrings and punch you in the mouth whilst it’s doing it. Having a cello player within their ranks isn’t an aesthetic gimmick; its inclusion is as fundamental to their hauntingly beautiful sound as all the other elements that make up this band. IAN released their incredible debut album Come On Everybody Let’s Do Nothing last year, and if you’ve heard it, I will assume you are as excited for this performance as I am. If you are new to IAN, prepare to see your new favourite band.

8. Nothing

I was really late to the Nothing party and actually only did a deep dive on them earlier this year before seeing them play a mind-blowing set at the Moth Club in London. Nothing play a melancholic form of aggressive and emotional shoegaze that, whilst vast and ethereal sonically, has a mournful and intense spirit to it. Nothing’s founder and frontman Domenic Palermo (former lead singer of hardcore punk band Horror Show) has had a life that would make for one hell of a documentary, and the music he makes now is clearly a reflection of the struggles and survival he has lived through. Nothing like a real experience. They will put you in a different dimension musically and immerse you in the world of their performance, go check it out.

9. Wildernesses

Another band who were featured in my Bands To Watch Out For article earlier in the year, UK shoegaze heavyweights Wildernesses are such an interesting and exciting live proposition. Releasing their debut record Growth in March, this album has been in weekly rotation for me ever since. What they have managed to create is a warm, dreamlike ambience which builds into these haze-filled journeys of melody. When combined with songwriter and frontman Philip Morris‘s deeply personal, narrative-driven lyrics and emotionally honest vocals, it’s a real smorgasbord of sonics and sounds that meld beautifully. Having never seen them in the live arena, this performance is a can’t-miss for me personally, and I would suggest putting it high on your list also.

10. Cult Of Luna & Julie Christmas

And in true Arctangent style, what a special headline booking we have here. In 2016, one of post-metal’s most highly revered and influential bands, Cult Of Luna, joined forces with noise rock queen Julie Christmas and produced one of the greatest post-metal concept albums of all time. Mariner is a one-hour, five-track masterpiece that explores a journey and exploration to the outer reaches of the cosmos. Through a dynamic range of stunning melodies, crushing harmonies and transient experimentation, they created one of the most diverse yet razor-focused pieces of heavy music ever recorded. And here we are on the tenth anniversary of this most special of moments in alternative music’s history, able to relive its magic and fully immerse ourselves in its brilliance. If you are a fan of music in any form, you can’t miss this performance.

11. Oathbreaker

When Belgium’s Oathbreaker released their 3rd full-length record, Rheia, in 2016, the subsequent tours predominantly featuring the material from that album, it must have taken an emotional and psychological toll on lead singer Caro Tanghe. The band’s six-year hiatus which followed didn’t seem all that surprising, had you witnessed the raw and traumatic nature of these shows, a break was most likely required as a form of recovery. An Oathbreaker live performance is more like a spiritual therapy session, where the caustic and uncomfortable meet the haunting and ethereal with an absolutely heart-rending effect. This will be one of very few reunion shows this year for Oathbreaker and will be an opportunity to see one of the most incredible live bands back where they belong.

12. Chat Pile

Oklahoma City noise merchants Chat Pile are little under three weeks away from releasing what I expect to be one of the albums of the year. A band who have been experimenting and dissecting the different layers of sludge for the past seven years, they appear to have found a grimy and unhinged groove that really suits the band’s clear intent of the bleaker, the noisier and the more jarring, the better. Amongst all the filth and chaos, however, is a band who haven’t stopped pushing boundaries and have been at the forefront of creating unique and interesting pieces of art that are as unconventional as they are moreish. If you haven’t heard Chat Pile’s Live from Roadburn, give it a spin, and I’ll see you up front on Friday night.

13. Leeched

In 2020, Manchester trio Leeched put out their sophomore record To Dull The Blades Of Your Abuse” A violent and uncomfortable mix of metallic grind and extreme noise, it was a sensory bombardment that felt disturbing and void of any joy or compassion, and I absolutely loved it. Sadly, Leeched then seemingly fell off the face of the earth and has only recently re-emerged in 2026 with a handful of club dates and a spot at Arctangent Festival. Attending a Leeched live show could be considered a form of self-mental sabotage, given its harrowing and destructive nature, but in my experience it’s always as entertaining as it is unmercifully soul-destroying, trust me.

ArcTangent takes place from August 19th to 22nd, 2026. For more information, visit the official website here.
