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. Like her previous work, Hedera’s intimate physical electronic music is simultaneously performative, rigorous, and visceral. It is likewise an assured new direction for Flanigan, whose duets with her unique hand-crafted wooden speaker feedback systems have been documented on 2014's Glacier and 2009's Amplifications, the latter called a "snow storm of a record" by New Music Box. Invested with the same powerful physicality as her speaker explorations, 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.
