"I started on a Synthi AKS in my school when I was 11 or so. I was very lucky to have an incredible teacher called Henry Sweitzer who taught Music Concrete, synthesis on a Synthi AKS and tape manipulation. It is the only real formal training I had. Musically, I am self taught and I play entirely by ear."
