An Evolutionary Music (Original Recordings: 1972 - 1979) compiles unreleased recordings from the archives of multiversal artist Ariel Kalma. Concerned as much with musicality as spiritual facility, Kalma's work vibrates aside fellow travelers along the great rainbow in curved air of the 1970s avant-garde. Ariel Kalma's boundary-blurring electronic music is heard here in radiant detail across a selection of work spanning his early free-jazz and spoken word trips to his infinite modular synthesizer and analogue drum machine meditations.
