Don't get your hopes up. There is virtually no score. Conti did a few minutes of source music. You would never know it's him. But on the plus side there is a great audio commentary from director/writer Paul Mazursky who does talk about Bill Conti off and on.
What I would get excited about is any possible release of The Big Fix (the Richard Dreyfuss film) from Twilight Time, because there is a very nice score from Conti that has never been released.
If memory serves, they both also happen to be very good movies.
After you've seen and (I hope) enjoyed NEXT STOP, look again at the opening scene in the subway, and see if you don't spot a nifty bit of Mazursky foreshadowing...
I just got it! I couldn't be happier with it! Great score totally isolated, no dialogue or sfx. Thank you again Mike Matessino, it's just like having a new unreleased Conti score. Also, Mike, thanks for BABY BOOM!
