Formed in 1980, Birdsongs of the Mesozoic play a unique mix of rock, punk, classical, minimalism, and free-form music, with occasional forays into even more unexpected directions, including spoken word performance and African-American spirituals. The group's diverse instrumentation has included piano, synthesizers, guitar, saxophones, flutes, and electronic and acoustic percussion. Birdsongs began as a side project by Roger Miller and Martin Swope, who were members of the Boston band Mission of Burma. They were joined by Rick Scott and Erik Lindgren for their debut recording, a self-titled EP, in 1983. With Mission of Burma dissolving at about this time, Birdsongs became a full-time band. The group released the LP Magnetic Flip in 1985 and an EP, Beat of the Mesozoic, in 1986. Miller left the group in 1988 and was briefly replaced by saxophonist Steve Adams, who had scarcely joined the fold before being invited to join the Rova Saxophone Quartet; Adams was then replaced by Ken Field. The new lineup released 1989's Faultline (which also featured Adams prior to his departure) and 1992's Pyroclastics for the Cuneiform label. Swope left the group and was replaced by guitarist Michael Bierylo, and this lineup continued recording for Cuneiform, which released the Dancing on A'A CD in 1995. Previously unreleased music by the band's original formation was also featured on The Fossil Record 1980-1987 collection, issued in 1993. This CD includes music the band composed for To a Random, a film by Boston filmmaker Michael Burlingame.
