Since Roseen was infected by electronic music in the early nineties, he has been heavily influenced by American techno from Detroit. The coordinates Berlin, New York, Birmingham and Brighton also play a significant role. All these influences are incorporated into his productions and DJ sets.        As producer, DJ, label co-owner and second half of the duo Ausgang, Roseen is largely unnoticed and active in obscurity. His releases are straightforward, raw and pushing. In his understanding, Techno must have a pure character. A naivety is inherent in the music; vibrancy arises from spontaneous and sketchy moments. This spirit is often tried to be imitated or copied, but rarely achieved. For Roseen, that is the challenge of making music but by listening closely, you can hear this in both his productions and DJ sets.
