Patronaat’s festival for adventurous and boundary pushing heavy music Complexity Fest returns to Haarlem July the 23rd, after the difficult last-minute cancellation last February.

After the disappointment faded away we decided we did not want to be silent for another year, and curated a line-up from the February edition, while planning to add some extra acts.

We’re happy that we can re-confirm AUTARKH III, LITTLE TYBEE, PLAYGROUNDED and VILDHJARTA. The Swedish heavyweights will close off the festival’s main stage with an exclusive show. With the addition of OTTO VON SCHIRACH and more names to be announced soon, this looks to be a memorable comeback.

Tickets are on sale now!


Complexity Fest 2022 has been cancelled

Unfortunately, and with a heavy heart, we have to deliver the bad news that COMPLEXITY FEST 2022 has been cancelled. Our highest priority has always been the safety of our audience, artists and crew, and due to the limited prospects regarding the COVID-19 pandemic and regulations we are unable to organize Complexity Fest 2022 as intended. We will, however, not give in; new Complexity projects are already in the works!

You’ll automatically receive a refund for your ticket(s) refunded by Ticketmaster within four weeks. The same goes for hotel reservations made through Ticketmaster; you’ll receive a full refund within four weeks after receiving this e-mail. Your hotel reservation will be cancelled automatically.

Furthermore, please check out if you’d like to financially support the Patronaat venue during these trying times. We really appreciate your support and promise that Complexity will return even stronger!

We thank you for your understanding, and hope you have been informed sufficiently. If you have any questions, please get in touch with us via



We’re happy to add Autarkh III, Playgrounded and Der Weg einer Freiheit to the line-up. Four new parts of the auditive spectrum we like to cover at our beloved Fest upcoming February. Tickets are on sale via Patronaat Haarlem!

Nevertheless, we are aware of the uncertainty surrounding live music events given the new surge in Covid-cases, but we choose to pull through and be optimistic about that we can finally welcome you all again after two years. Of course we will keep one eye on the ever-changing situation, and keep you updated if things might change.


AUTHOR AND PUNISHER announces new album Krüller

Author & Punisher, the alias for visionary San Diego musician-meets-mechanical engineer Tristan Shone, returns with the melody-laden new album, Krüller, featuring a suite of upgraded machines, a distilled vocal process and a handful of guest players including Tool’s Danny Carey and Justin Chancellor. The album will be released on Relapse Records on February 11.

A taste of the eagerly-awaited record arrives with today’s release of “Drone Carrying Dread,” and the accompanying, graphically-saturated video. The clip was directed by Monte Legaspi and features illustrations from album cover artist Zlatko Mitev.

Part of the Krüller revamp included refining the machines that have become synonymous with Author & Punisher. As a result, Shone is also launching a bespoke audio gear company called Drone Machines to coincide with the release of Krüller. The gear company launch follows nearly two decades of Author & Punisher honing in on his craft – meticulously inventing, machining, experimenting, and creating custom musical instruments for his incredible live performances and recordings.

Krüller pre-orders are available now with the 8-song, 52 minute collection available on a selection of limited-edition vinyl variants, CD, cassette and digitally.


Conjurer will not play Complexity Fest 2022

Unfortunately, Conjurer have to cancel their performance at Complexity Fest 2022.

But on a brighter note, we will announce some additional bands that we are really excited about soon!



After releasing ”när de du älskar kommer tillbaka från de döda” earlier this year VILDHJARTA announces the release of their much anticipated new studio album, “måsstaden under vatten”, which will be out October 15th, 2021. You can also listen to two new tracks, “kaos2” and “toxin” on all digital platforms.

At 6pm CET / 12:00 noon ET / 9:00am PT make sure to head over to Century Media Records youtube channel to check out two visualizer clips that are giving you more insight into the stunning album artwork.

With a decade between releases, vildhjarta remain as inscrutable and as close to anonymity as a band can be. Their down-tuned, staccato riffs and pulverizing grooves are the sound of music stripped to its essence. Yet, the Swedish collective’s long-awaited album, “måsstaden under vatten”, is far more than a recitation of djent values. Clocking in at 80 minutes, it thematically picks up where the dark Swedish fable of 2011’s “Måsstaden” left off and delivers on the promise that record hinted at. Says the band: “Art happens when art happens.”

Since dropping a minute of new live music in 2016, the band’s focus has almost entirely been on the new album with drummer and now noted producer, Buster Odeholm (also known for his work with Born of Osiris, Shadow of Intent and drumming with Humanity’s Last Breath amongst others) heavily involved in the production, mixing and mastering of the music. Visual artist Rickard Westman, who did art for VILDHJARTA’s debut as well as their “Thousands of Evils”-EP in 2013 has also returned to the equation to reprise his disturbing visual iconography that continues to tell a tale of a mythical, dark world far away from ours.With finally a new album on the horizon, we are over the moon given the fact that they are coming to Haarlem for an exclusive show.

Dragged Into Sunlight forced to cancel performance at Complexity Fest 2020

Hey it’s Thom here with an important update on our upcoming fest.

As some have heard rumors I’m here to confirm them: beyond our control Dragged Into Sunlight won’t be able to play their show. We’re close personally too and also because of that extra bummed about this one. The band just released their own statement:

“Dragged Into Sunlight will not be appearing at Complexity Festival this year owing to personal circumstances. We never want to disappoint. The festival is a killer event organised by some good friends, so we hope that you’ll attend.”

I hope we can make up for it within Patronaat’s walls anytime. All the best wishes to them!

With that being said, we wouldn’t be Complexity if we didn’t come up with a worthy replacement and after ‘the great hunt’ we present you one of the most exciting experimental black metal bands hailing from the UK: Lychgate. You might know them from the former Blood Music roster as I did, and they are about to release a new EP this March pushing the boundaries of everything you know black. “Progeny of the Singularity needs to be heard to be believed, and even then, probably won’t be believed”. Here’s the updated poster and let’s celebrate this musical ride soon, so soon now!

Listen to Lychgate HERE.
