Yannick was born in France in the early 80's and grew up in Geneva. In the late 90's, he got into Chicago house and listened to djs such as David Morales from New York and Carl Cox from UK. He later discovered the "Sound Of Detroit" through the cult anthem "The Aztec Mystic - Knights Of The Jaguar, produced by Dj Rolando. A child of house music from the ninghties, Yannick owns a large collection of music whose driving force is a constant search for original sounds. His first work came to life in 2000 inspired by video games, and 2 years later he started working on Reason with his cousin during a holiday in the south of France.

In 2009 in Geneva, he launched his first professional musical project, the Teknologik label, with his long-time friends Romano & Vincent. When he then moved to Brussels in 2011, Yannick set up his own label BlackWallRecord with his friend Fabrice Wilkin with an aim to develop the local techno scene. It was around that time that 'Klengmann' the producer first entered the scene, and started sharing his own productions. In 2012 he produced his first album "Like A Puff Of Air" as well as several remixes on Teknologik and BlackWallRecord.

Klengmann’s music takes from a wide array of techno genres from dark or melancholic to happy, while some are more straightforward minimal dancefloor tracks with a groovy bass and traditional beats.
