Probably old news but saw this in the AquariusRecords.Org weekly mailing list. Film Score Monthly has done a repressing of the THX 1138 soundtrack.

THX 1138 (LALO SCHIFRIN)
OST
Finally here! We have been waitin' for this reissue to arrive for eons (well, at least Cup has!), and it's so well worth the wait. This is the original soundtrack to George Lucas' 1971 feature length debut THX-1138, a chilling, near-future dystopic cult fave shot right here in SF. Although Lucas decided to handle this film's restoration for the dvd release in much the same unfortunate way that he did for Star Wars - namely, by adding numerous quite significant (often intrusive and questionably necessary) CGI 'enhancements' and revisions - Lalo Schifrin's soundtrack has aged quite gracefully, and this release even includes some numbers he composed for the film that did not make the final cut. We love Schifrin's work, and this is no exception. It is considerably different from his many other sountracks (Bullitt, Dirty Harry, Enter The Dragon), but then again this film is considerably different. Imaginative, haunting and incredibly effective, his score perfectly complements Walter Murch's innovative ahead-of-the-curve sound design (it would be great to have a cd of that!), and together they play a vital role in each scene and in the film's overall impact. Starkly contrasted with the film's predominantly icily sterile visuals, it's an ever-shifting aural kaleidoscope of grand symphonic strings, menacing drones, blats of brass, imposing choral assemblies, bursts of Latin jazz, early synthesizers and electronic explorations, solitary woodwinds, percussive African rhythms, and avant garde sound collage... topped with a deliriously giddy "Be Happy" sing-song jingle cherry on top. Richly atmospheric, melodious and dissonant, and deceptively unsettling. Highly recommended... and not just for film score buffs! Limited pressing of 3000, but it has been out for a while, so get it while you can!
