Original copies from the Eighties.

Cambridge Street Records was created in 1985 by Barry Truax as an alternative to commercial publication that specializes in computer and electroacoustic music by Canadian composers. Each Cambridge Street Records production is personally supervised, both artistically and technically, by the composer and features the musical use of new audio technology such as digital sound synthesis, multi-track recording and digital signal processing. The first two releases in 1985 were an LP entitled Sequence of Earlier Heaven with four of Truax's own works and an LP entitled Aurora of electronic and computer music by Queen's University composer David Keane. Each disc was accompanied by a Teacher's Guide prepared by the composer in order to make it more accessible for use in schools.
