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!

Aug 20, 2021


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.

Thank you for visiting Complexity Fest 2020

A sincere thanks to all of you wondering and wandering colourful souls coming from seemingly everywhere this weekend, and thanks for bringing your attention and positive energy! Arigatou, merci, takk and such to all the acts that graced our 3 stages giving what they got and for just as well blending in happily with most of the aforementioned around all the show madness.

We’ve witnessed a delightful array of memorable, engaging moments and performances spread throughout the fest. Last but not Liszt very much bedankt to the really hard working crew in Patronaat and everyone involved, giving us as the Complexiteam the opportunity to blend in with all of you while knowing each and everything got taken care of and looked after so well.

We’ll continue the adventurous heavy music train to newer heights with some first next stops this month still. All the best for now and we’ll use this evening furthermore as how this day was mentioned in that Holy book while checking the audio-visual aftermath.

Practical Info for Complexity Fest 2020

Below you’ll find the full time schedule. Doors open at 13.00 and Our Oceans will grace the Aristides Stage 2 at 13.30. Make sure to catch this amazing band with one of their debut shows!

Sadly Dragged Into The Sunlight have cancelled their performance at Complexity Fest 2020 due to personal reasons. 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.

Be aware of the fact that Patronaat Haarlem is a PIN ONLY venue and it is only possible to pay with debit cards at all bars, wardrobe and the festival merchandise booth. Only the common creditcards will work and it possible that a lot of foreign creditcards won’t. ATTENTION: it could be the case that your favourite band only accepts cash and doesn’t have an option to take cards, so make sure to bring some extra cash anyway.

The venue Patronaat is addressed at Zijlsingel 2 in Haarlem.

  • It’s a 10 minute walk from Haarlem train station. Also busses 2, 3, 73, 81, 300 and 340 will take you close to the venue.
  • Coming over straight from the airport? Bus 300 will take you from the airport to the Haarlem city centre the quickest
  • Traveling by car? There’s a big parking garage close to Patronaat Haarlem, follow signs to ‘Raaks’. It’s open 24 hours, and there’s an evening rate at € 2,90 for the entire night (starting at 19:00).

All band and (new) Complexity merchandise, Pelagic Records and SmithsFoodGroup distros, and catering is presented in the loading dock on the ground level.

For the hungry folks, we are happy that JUST LIKE YOUR MOM will provide us again with some of the most delicious vegan food we ever had. For all the meatlovers out there, EEF EN LIEN will be there for you in the loading dock. Good to know: we’re in the city centre with a supermarket on the other side of the road (open until 10pm) and several other options for meals.

As announced we will have a pre-party on the day before the festival, Friday February 14 (doors 19:00). And with BEATEN TO DEATH, ASTROSAUR and MARY FIELDS we have a line-up that guarantees you get a proper warm-up, if not ending up totally wrecked. Join us for this one! IMPORTANT NOTE: entrance for the pre-party is free on showing your Complexity Fest 2020 ticket. You know people that just want to visit the pre-party themselves or bring their Valentine without a ticket? That is possible for only €10,- a ticket. You can buy a separate ticket here.

Time Schedule:
19:30 doors open
20:00 Mary Fields
21:00 Astrosaur

Still in search for a place to sleep? Our partners at STAYOKAY Hostel and the NIU Hotel have still rooms available.

We cannot wait to welcome you all!

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.
