This is #12 in Sub Rosa's limited edition Framework series -- an extension of their Concrete Electronics Noise series. Antimatter is the sound work of Xopher Davidson -- an ongoing exploration into the material of sound. Xopher builds his experiments in electronic sound from a basis in painting, photography, and film, and through an interest in electronic circuits going back to building radios and homemade circuits as a kid. Over the last 11 years he has built and explored the sound world of a homebrew modular synthesizer comprised of surplus laboratory equipment: various oscillators, pulse generators, filters, and an "analog computer." He has released four albums as Antimatter: Transfixion, Antimatter vs. Antimatter, Our Lady of the Skies, and Reset. As an audio engineer, Davidson has worked on projects composed/performed by: the League Of Automatic Composers, John Cage, Marcel Duchamp, Subtropic, Diamanda Galas, Kid 606, DJ Rupture, Darwin's Bitch, Once 11, Mix Master Mike, Hans Grusel, Phoenecia, Jonah Sharp, We, Zbigniew Karkowski, and Iannis Xenakis. Zbigniew Karkowski is one of the most influential electronic music composers working today. Linking the worlds of modern composition and industrial music, he is a pivotal figure in the development of advanced noise. Constantly on the road, he is a frequent performer on the geographical fringes of experimental music culture as well as a mainstay on the established festival circuit.
