Unreleased rarities from Ariel Kalma's personal archives recorded in the legendary GRM's Studio 116 during the '70s. Born and raised in Paris, Ariel Kalma started playing the recorder and saxophone at a young age. After successive studies of computer science, music and art in Paris he performed in various concerts from middle-age music to free jazz duo. After learning circular breathing on soprano sax, Ariel could include those endless notes into his own long-delay effect system. In France during the mid-1970s, Kalma worked as a recording assistant at legendary Groupe de Recherches Musicales (INA GRM) studios, where Ariel recorded some of his compositions in Studio 116; the same music laboratory where Luc Ferrari and Bernard Parmegiani also recorded their pieces.
