Four years in the making, our reissue of Laurie Spiegel’s now-classic The Expanding Universe is finally due out September 25, 2012.

The focus of this collection is the same as it’s always been since its original Philo LP release in 1980, tracks composed between 1974-77 and realized on the GROOVE system at Bell Laboratories.  For this reissue, however, Spiegel went back through all of her original tapes from the period, painstakingly retransferring and mastering them newly for this edition.  The original LP contained only four tracks.  This new edition will present a near-complete collection of her work on the GROOVE system, adding an additional 15 pieces to the original four, most never before released.  Of those few previously released, like “Drums” from Obsolete Systems, one will notice a remarkable improvement in quality and clarity.  Other well known tracks included in this collection include “Appalachian Grove I-III” (Part I of which features on well known compilations of electronic music) and “Kepler’s Harmony of the Worlds”, which was included on the Voyager space shuttle’s golden record (making its first appearance on CD here).  Not to be confused with a shiny-new remaster job of an old favorite, every effort was made to preserve the sound as closely to the original masters’ full-dynamics as possible.

The set will arrive as a 2-CD set, single limited-edition LP reproduction of the original LP with one bonus track, and a digital download.

Full tracklisting and pre-order available available now.
