Tonic Train is the longstanding experimental electronics duo of Sarah Washington and Knut Aufermann. The combination of Sarah's homemade circuitbent instruments and Knut's feedback mixer creates a rich spectrum of fundamental electronic noises. They combine two methods of electronic music production: the appropriation of electronic circuits to make components produce otherwise unwanted sounds and the improper use of audio equipment to make it feed back. This includes a specific interest in radio technology, and micro transmission is an important part of the sound field they create. Since forming in the year 2000, Tonic Train has been incorporated into a range of diverse musical projects including a feedback ensemble with Otomo Yoshihide, Toshimaru Nakamura, Nic Collins and Xentos 'Fray' Bentos, trios with Munich Philharmonic violist Gunter Pretzel, Viennese video artist Billy Roisz, Japanese sound artist Haco, and groups such as the Resonance Radio Orchestra.
