Substrate is an improvisational electroacoustic group consisting of Laura Thomas-Merino on cello, M. Cera and RS-232 on electronics, and Jen Boyd on field recordings. The project began in 2006 with the creation of a piece for Soundwalk 2006 in Long Beach, CA which consisted of a 10-foot tape loop with sounds of cello, electronics, birds, and a plucked heater. This will be their first live performance together with one member, Jen Boyd, performing via the web from her home studio in Oakland, CA.
