AArkaos Live @ Acidelics 10 Y Anniversary

"Tribe Tekno Tempest" is a 40-minute aural assault crafted by the notorious sound system traveler crew known as Olstad Sound. This blistering live set captures the ferocious energy of The Tribe's legendary tekno raves and illegal warehouse parties.
From the murky atmospheric intro, thunderous tribal drums and bone-rattling bass tones signal the coming storm. Waves of abrasive industrial textures and distorted synth riffs whip up a relentless frenzy, driven by Oby One signature hypnotic, cyclical rhythms.

 Après de longues recherches, nous l'avons fait ! Nous l'avons trouvé, « le pays des merveilles ».

Êtes-vous prêt à vous lancer dans une magnifique aventure en compagnie des 
 Troll2tek / LBS / LKS / As2tek / Plasmatek.

Au sein du terrier du lapin blanc. Les sounds se sont préparés et ont sorti leurs plus puissantes armes, afin de faire trembler la reine rouge et ses sbires, et d’enfin pouvoir danser et chanter en toute liberté

UFO #57 Spring Session [Stefan ZMK & OdS#23]

Linked up with Jorys from Zkouška Zvuku at my LXRecords studio – had a proper hang, some laughs, and jammed out on the decks for a bit. 😁
The result? A spontaneous little minimix – short but packed with vibes and good energy! 🔥

👉 Give it a listen and let us know what you think! Thanks!: )
