Obvious question. How much score was missing from the original CD? I'm sure there will be alt versions too.
I wonder about this too but Williams is an exception to my usual preference for (mostly) curated albums as opposed to C&C scores because his albums tend to rethink his scores in a way that can sometimes hide their architecture and development. My guy clearly knows where his bread is buttered and I generally enjoy his albums, but I've come to the realization in the last few years that for me what's missing is beside the point. I want to hear his ideas from point A to point B.
John Williams generally restructures his film scores into stellar albums, but he isn't perfect - Not every OST album is a shining achievement in arrangement.
I think WOTW is one of the least successful OST albums he ever put together. The order the music is presented doesn't do it any favors, the looping and repeating music doesn't enhance anything, and the narration is very bothersome.
Just re-ordering the highlights he chose for the OST into chronological order makes a huge improvement. All the additional cues he elected not to include on the OST really help the score breathe, too.
I was tempted to get the original soundtrack release, but when my favorite part of the score appeared on the 'Indiana Jones and the Kingdom of the Crystal Skull' soundtrack (Hidden Treasure And The City Of Gold), I didn't bother.
I might try for this release if it does what everyone here hopes it will do.
