Karl Herrstein Paris From South Paris, and first trained as a bassoonist, Karl Herrstein was more used to theory behind classical music than actually writing them. It was only years later, when joining the BPM crew that friends taught him about the universe of electronic music. The first glimpse at music production, inevitably led him to start crafting music. Being influenced by artists and genres ranging from French Touch to industrial equipment sounds, he focuses on creating music with dreamy melodies and harmonies.
