Brainwave Music

Originally recorded at Electronic Media Studios, York University and Warehouse Recording Studio, New York. For this reissue, the original LP is supplemented with an additional LP containing an unreleased 1977 live recording of Rosenboom’s “On Being Invisible”, in which the composer himself performs on an array of electronics that are fed information from his brainwaves. Stretching out over 40 minutes, the piece begins in similar territory to “Portable Gold and Philosophers’ Stones” but eventually becomes far wilder, building up to pointillistic bleeps and dense layers of electronic fizz that unexpectedly cut to near-silence. As Rosenboom explains, the piece creates a situation in which the “performer’s active imaginative listening became one of the ways to play their instrument, as well as an active agent in how self-organizing musical forms might emerge. Extensive annotation of equipments and processes used are included on release.
