Excellent thread! Here are mine:
1. Ascent the Scaffold (Miles Davis)- not only is this a very sexy soundtrack, it is an undeservedly neglected Jazz masterpiece. The CD (Fontana) sound is just okay, however, soundtrack has been re-released on Vinyl (a must, esp. for Miles Davis/Jazz afficianados)
2.The Big Blue: skin-tinglingly good. I only wish they would bring out a 24/96, SACD or vinyl remaster
3.Diva: uses a few tracks from the opera La Wally, but the title music by Vladimir Kosma is quite beautiful (nice reverb effect). Other pieces on soundtrack can be skipped over
4. Lost Highway (esp.David Bowie tracks)
5. Merry Christmas Mr Lawrence (chinese compositions with David Bowie vocals)
6."White-Heat" by Jazz at the Movies Band: a collection of Film Noir soundtracks. An LP was recently released which is better than the CD. Again, mandatory for Jazz fans
8.Eric Korngold and Rosza movie scores
Many more - these are a good start.
Thanks to all for sharing.
