The musical career of Thomas Hauser started in his early childhood. He had several years of accordion lessons and later switched to keyboard. He didn't want to focus on keyboard instruments only though which made him pick up the guitar, learning it all by himself.
He played in many different bands of different styles of music, e.g. pop, indie, punk, grunge and much more. Nevertheless he now and then needed time for himself to calm down and relax all by himself in the studio. That was the first slight hint of his future project SINE.
