Kris Vanderheyden (Halle, Belgium), known by his stage name as Insider, is a Belgian techno and electronic music producer. He is considered one of the leading pioneers of the Belgian originated techno electronic dance music scene.

He was born of a French mother and a Belgian father, a trumpet player who was a Latin music lover and owner of an enormous record collection with artists spanning from James Brown to Donna Summer and genres from Classical and Jazz to Zydeco.

While growing up, Vanderheyden spent most of his childhood with his grandmother and an uncle who was a fan of Led Zeppelin, Pink Floyd and The Sex Pistols. This mixture of musical genres came to influence his music career later in life.

At the age of 16, Vanderheyden took a position at a local record store in Halle Belgium called Eddy's Records where he became even more consumed with music. After saving enough money from his job, he bought his first synthesizer, a Roland W30 and started to compose his very own music in his bedroom.
