The ghostly beat is by a malfunctioning tape deck and the voice-cloud is by Lesley Flanigan, layering herself against the unceasing pulse. The result is Hedera, a vivid new extended recording on Physical Editions from the New York-based electronic musician and instrument builder, and an elegant new platform for the powerful vehicle of Flanigan's voice. Invested with the same powerful physicality as her earlier explorations with speaker feedback, the two tracks of Hedera move her sculptural approach to sound towards a new synthesis, a gorgeous new setting for her voice that finds itself halfway between the equally hallowed spaces of the experimental music hall and the dance floor.
