Then came Dutoit's split from the MSO, and the recording disappeared, unfinished.

I just checked cdplus.com's list of future releases, and there it is: http://www.cdplus.com/cdplus300/default.asp?isle=0&action=detail&code=446691

A Theodorakis disc featuring Zorba, on the Decca label.
No artists listed. So I can only speculate this is the Dutoit disc.

The price ($16.99CDN) is in line with other Universal Classics new releases, as opposed to the price for re-issues.

With some fillers recorded recently by Dutoit and the Philharmonia Orchestra in London.

The Zorba ballet is only some excerpts of about 30-35 minutes for female vocal, chorus and orchestra.
Other than the thematic material, it has absolutely nothing to do with the original soundtrack.
This suite of excerpts opens with a wild scherzo-like movement for chorus and orchestra.
Follow some decent enough songs for the mezzo-soprano.
There's a frantic cue for orchestra and chorus worth the price of the CD.

Then Zorba's dance and variations on it for full orchestra and bouzouki, later reprised with chorus.

As you might expect, the Montreal violins never produce a lush string sound, all the more obvious as the fillers are played by the Philharmonia Orchestra which achieves some golden-toned strings. Rythmic consistency within the Montreal band is amazing. Every little percussion, every tiny sound is exactly where it should be.

I've never been a Dutoit fan, but what he achieves here, especially in the faster movements, is as Timmer would say, genius. The orchestra sounds as one entity even in the most frantic parts.

The whole performance is bass heavy though. Recorded sound doesn't help. Up until 1994 when Ray Minshul produced the Montreal recordings, the sound at the top was crisp. Ever since Minshul retired, producers Andrew Cornall and Chris Hazell have not been able to match Minshul's productions. Their CDs have always been rather dull-sounding, with excessive lower end, and dull, muddy upper registers.

The Philharmonia fillers are unremarkable. Well played, nice to hear, but completely forgettable.
