Glyphs (Music from Martin's Tape Archive) Glyphs (Music from Martin's Tape Archive) is a new quadraphonic concert work comprised entirely from unreleased and rarely heard reel to reels from the archive of electroacoustic composer Martin Bartlett, which were digitized by Luke Fowler as part of his research process in making Electro-Pythagorus. The works included in this composition cover Bartlett's entire career highlighting the diversity of his electronic compositions; beginning initially in the 60s with homemade analogue devices, working with Buchla boxes from the 70s, and from the 80s onward dedicating his energies to FM synthesis using self-designed software environments exploring microtonal tunings tables and the interaction between computers and performers. Martin taught electronic and world music at Simon Fraser University, Vancouver. Bartlett was a founding member of the cross-media artists run space The Western Front, He was part of an international live computer music scene and also wrote and performed shadow plays across Europe with the Canada Shadows. http://ek.klingt.org
