Well, this Vangelis Collector site provides a glimmer of an answer to the Alexander conundrum (see previous post.) While it mentions a recent Ebay auction of the disc, it doesn’t indicate that the price was anything unusual about it. But then, this was a few weeks ago. It seems there are some music cues on the disc that are in the movie but not on either of the two released soundtracks. That’s cool, but just how good are those cues?
Here, too, is some information about the score (scroll down a little for the entry.)
