Description

This LP presents Laurie Spiegel’s Harmonices Mundi, a landmark in early computer music that makes Johannes Kepler’s 1619 vision of a “music of the spheres” something you can listen to. Produced at Bell Laboratories using computer-based synthesis, the composition translates planetary motion into a dense, evolving sonic field—part drone, part glissando-driven swell—where tonal clusters rise and fall with an almost gravitational pull. Selected by Carl Sagan for inclusion on the Voyager Golden Record, it became one of the first works of computer-generated music sent into space. This record marks its terrestrial release, foregrounding Spiegel’s distinctive approach: treating the computer not as a purely analytical tool, but as an expressive instrument capable of merging mathematical structure with intuitive, emotive sound.
