In 1985 Dag started DJing at the „Music Hall“ in Frankfurt where he had a residency for two years. He left because he had a conflict with the management and moved to a new small club in Saarbrücken called "Mirage", where he played for a couple of months before he left to "Aoxomoxoa“ in Wiesbaden. After his Wiesbaden adventure he returned to Frankfurt tot play at "Vogue“ (which would later become the Legendary „Omen“). Here he also had some problems with the management because the women, the majority at Vogue, did not like his choice of music, which was influenced by the industrial sound of those days, such as "Nitzer Ebb“, "Front 242“, "Skinny Puppy“. In March 1988 he started as resident DJ at the "Dorian Gray, a big club at the Frankfurter aiport, because Sven Väth left the place. For 5 successful years he played together with Thorsten Fenslau on the Sunday mornings. In the nineties he had a monthly residency at "Club UK" in London and played at the Tribal Gathering events.
DJ Dag founded the project "Dance 2 Trance", together with Jam El Mar, which resulted in the release of "Power of American Natives" for which he received a golden record. Together they also released the track "I will fight no more forever" under the name "Peyote", which still has a cult-status in the scene.
