About LE NOTTI BIANCHE & ANNA
The Original master tapes were missing and it was only possible to save these valuable Rota scores using the film soundtracks with all the imperfections involved (noises, voices, etc.).
The music from Anna (1952) has never been released before.
A [url=https://www.discogs.com/Nino-Rota-Greatest-Hits/release/6156452]later release[/url] replaces these M&E (Music & Effects) and full audio soundtrack cues with newly recorded versions of the scores.
