Harmony & Soul & Groove – just some aspects of Ralf’s uplifting music. With a feeling for the right vibe, Ralf GUM played at more than 250 German and international spots. The "Airport" (Wuerzburg/Germany) got the living-room for his interpretation of house in 1998. Since then he captures the enthusiastic crowd every Friday night and played alongside with world’s top Guest-DJs. Since 2006 you can enjoy Ralf’s unique sound at "Climax" (Stuttgart) and since 2008 at Frankfurt’s new in-location APT as well.
