Stefan Mallmann aka Complexx303 saw the daylight of the sun to 02.03.1979 in Oberhausen living (Ruhr district). Grown up in upper living in Essen he came for the first time at the beginning of the 90's by a friend in the neighbourhood in contact with acid - house. This Style became its constant companion. Fascinated of the tones and the enthusiasm of the pianos and vocals did not release it. The first way into the electronic music was found. Later the entrance came into the scene and it gave still more to discover. The interests in music could not be braked. Its first musical going attempts Stefan made 1998 with his first machine, for a MC-303. It was long in coming not, when Stefan played for the first time 1999 before public live. It a little later decided to lead with its best friend Stefan Tretau Comlexx303 with two of Combo further. Compexx303 was born... With enthusiasm of the machines and the sound they had a little later a small instrumentation together. From now on one could experience Complexx303 in different clubs in North-Rhine/Westphalia and also outside of live. Among other things in the star club - Muehlheim, fusion club - cathedral, Pornclub - Essen, Chism Club - Duisburg and some Tekktribe Parties in Greven. 2002 created the two with a friend Ümit Han the "river on" Parties in the Turbinenhalle - upper living. Own Acid Parties "Our Fukin ' Acid" was program and stood on the agenda. The Parties was full successes. The three had counted never on the fact that it would boomen in such a way. Sounds of club in a region discotheque functioned thus, those to Parties were gladly visited. Complexx303 noticed 1 1/2 year later that it was more important you to concentrate on music in the actual sense than own Parties to organize. They produced further music some directions and played further live in differently clubs. Beginning of 2005 the two and everyone separated went its to own way, with which none existed out for Complexx303. Stefan Mallmann resumed the project Complexx303 alone in various clubs. Among other things gate 3 - Duesseldorf "hang the dj", fusion club - cathedral "Acid Wars", Aquatower - Duisburg "Symphonic" and Overloadclub - Solingen. At present Stefan discovers ever more from the electronic music and produces further tracks of minimal, house to techno and acid. No borders are set to it. That noticed also Robert Babicz aka rob acid. The Stefan`s track "Gesundheitstelefon" on "junkfood records" released. remains waiting for which still happened. Liveacts by Complexx303 under the slogan "muzik is - A state OF mind" remain.
