Computer music pioneer Laurie Spiegel's 1980 album The Expanding Universe is being reissued and (appropriately enough) expanded, by Unseen Worlds. This new version is due out in September, retransferred from the original tapes and remastered by Spiegel herself.
The Expanding Universe was composed by Spiegel in the late 70s, on the GROOVE system at Bell Labs, and for this release 15 mostly unreleased tracks have been added to the original four.
Spiegel factoid: Her "Music Of The Spheres" (an interpretation of astronomer Johannes Kepler's Harmony Of The Worlds) was included on the golden record that was launched onboard the voyager spacecraft.
Unseen Worlds will release the record on double CD and on vinyl on 25 September. More details here.
