Ralf Hedemann aka Courtis had his first contact with electronic music in early 1993. Ever since, techno has become his lifestyle. Soon he started his journey as a DJ in smaller Clubs around Bonn and Cologne. In the beginning his musical style was straight techno but developed over the years to a more minimal and reduced form of this genre. As time passed, his interests expanded and today he plays every kind of electronic music, so it has become hard to put a name on his style.
Since the beginning of 2010 he has released on labels like Aspekt, Circle Music, Harthouse and Kopfmusik
