Stefan Tretau´s musical journey begins in Mulheim an der Ruhr, Germany where he was born. Having spent some time in Switzerland Stefan returned to Germany with a head full of ideas and inspirations, which he found in electronic music. Influences of the time included producers such as Rob Acid, Tesox and Phuture 303. For Stefan forward thinking was the only thinking and in 1999 he teamed up with one of his closest friends Stefan Mallmann to form the acid combo called “Complexx 303”. The duo went on to play live at many respected venues across Germany such as the Chism club and Fusion.
