After they were forced to cancel due to the pandemic, we are more than happy to have manmachine AUTHOR & PUNISHER back. In the industrial music and metal sculptures of Tristan Shone man and machine melt together. The San Diego-based robotics engineer with a degree in sculpture literalized the idea of sonic sculpture, fusing the ethereal and the physical into a brand new vision, captured on several recordings of which the lauded album ‘Krüller’ is the most recent.

We decided to invite the French post-hardcore group BIRDS IN ROW back to Haarlem after their amazing headline show in November. We cannot wait to present them to you yet again. BIRDS IN ROW has been at the forefront of the hardcore genre for over a decade. Starting out as a band with a sound that can be compared in subtlety to two paving stones rubbing against each other, the band sets the bar incredibly high with their most recent album ‘Gris Klein’.

IRON JINN is born from the chemistry between guitarists Wout Kemkens (Shaking Godspeed) and Oeds Beydals (The Devil’s Blood, Death Alley). Inspired by the San Diego Takeover at Roadburn 2018, the band, completed by Bob Hogenelst (Birth of Joy) and Gerben Bielderman (Pauw, Bieldermann), produce dark and ominous, yet freaky songs, as proven by the first single ‘Soft Healers’. This song is taken from their “frantic double LP” debut, to be released by Stickman Records (Motorpsycho, King Buffalo and Elder) in april 2023. We are very curious to hear more!

Team Complexity used to be, and still are, huge fan of Dutch progressive metal outfit Textures and that’s actually the reason why we are more than happy to host CROWN COMPASS at this years festival. Crown Compass is the brainchild of former Textures and Illucinoma guitarist Joe Tal, whom linked up with none other than Daniël de Jongh (ex-Textures and CILICE), bassist Robin Zielhorst (ex-Cynic, Exivious and currently with Our Oceans) and drummer Yuma van Eekelen (ex-Pestilence, Exivious and currently with Our Oceans). After two years of teasing, the group finally released their debut album ‘The Drought’ in april. A 9-song juggernaut which is heavy and intricate, while catchy and groovy at the same time.
