Hagen Bergmann (Hagen B) started his career in world renown Tresor club, the old one - of course. He soon became resident of that institution but was rather attracted to the (housy) Globus floor at ground level than the (technoid) torture chamber downstairs. He also played in clubs like the legendary E-Werk (Dubmission), performing alongside Joey Beltram, Eddie Flashin' Fowlkes, Mike Grant, Juan Atkins, or Trevor Rockcliff. In more modern times he rocked Suicide Circus, Tresor Berlin, Bar 25, Cookies, Arena Club, Stattbad & The Villa, Club 103 and the international side of the Easyjetset.

Sound of Hagen Bergmann (Hagen B.) and "2ND BERLIN SCHOOL" - a sound that can instantly be perceived as House and Tech, but also pleases body & soul and Minimal with new, refreshing noise made in the 21. Century. It takes the best from the old Berlin club sound and makes it ring fresh and new.
