DEREK HOLZER / INSTRUMENTS
I make live improvisations on self-made, analog sound equipment. I do this because I never learned how to play the guitar, and because no one can tell you that you are playing an instrument "wrong" or "badly" when you have invented it yourself. My live sets are often quite loud, as I believe that the primary physicality of sound is far more important than the meager, extra-sonic avenues provided by (over-) intellectualization.
...My two primary instruments are the TONEWHEELS optoelectronic synthesizer– inspired by some of the groundbreaking 20th Century electronic music instruments such as the ANS Synthesizer (Evgeny Murzin USSR 1937-57), the Variophone (Evgeny Sholpo USSR 1930) and the Oramics system (Daphne Oram UK 1957)– and the self-built Macumbista Modular analog synthesizer, which reinterprets and hybridizes the forms and functions of the Serge and Buchla systems of the 1970s
