Stefan Kaufmann (Solingen, 1960) began with playing guitar which wasn’t to succesful. At the age of 13 - 14 he wanted to play drums instead. He assembled and built a foot machine, he didn’t have any cymbals but a snare. Later his father gave him a real percussion set. It was by now Stefan started to practise. Day after day he dashed the drums. After a while he joined a band with Jörg Fischer called "Frenzy". It was not a succesful combination and after a frightful appearance he took his drum-kit back to the cellar and continued practising. He tought himself. It took about one or two years until he made his next appearance in a band called "Fathers Of Intention", again with Jörg Fischer on guitar. This was beginning for Stefan Kaufmann before he came to join Accept and stayed for a long time.
When Stefan Kaufmann's back problems once again forced him to stop playing drums in the middle of the recording sessions for "Death Row" in 1994, Accept decided to continue with Stefan Schwarzmann as a temporary replacement.
Stefan has been producing artists like, Rough, Casanova Silk and of course U.D.O. He also plays guitar in U.D.O.
