Wowa Effect
Music producer, Live techno performer, Germany
Wowa Effect aka Wowa Barssukov revives the art of creating music with knowledge and analog instruments. His unique tracks originate from a combination of retro synthesizers, drum machines, and samplers. He transcends mood into music, no exact recreation possible when playing live; all sounds originated by hand. His debut performances were underground raves and house parties in 2018.
His musical knowledge is based on classical Russian music education. Growing up in Siberia in the ’90s, his childhood was filled with communism, the sense of upheaval, and the upcoming of an underground raver scene. He started his electronic music journey under the name ‘Limpfate’ in 2017 first by creating his tracks with Ableton Live, until growing bored of the unengaging production. He then discovered analog synthesizers and drum machines, which shaped the sound of the electronic music scene in the ’90s, and spent countless hours on mastering the complex devices.
This art of performing allows Wowa to explore the vast horizon of electronic music. Therefore his sounds vary from ecstatic electro over the groovy house to deep techno. His tracks take the listeners on journeys through the unknown, full of surprising details.
When watching Wowa perform, you will notice a set of blinking lights, cables, and his straight face. When Wowa plays, it’s without exception, live.
Wowa now lives in Berlin, close to the pulse of the original German techno scene with its renowned Berghain.
