Hear Tracks From the Original Score for '2001: A Space Odyssey' That Kubrick Replaced at the Last Minute "Film buffs are familiar with the story surrounding 2001’s iconic score. For those who aren’t privy, the story goes that Kubrick hired North, who he had collaborated with twice prior to the release of 2001, to compose the score. However, as he began editing using the classical backdrop that is now inseparable from the film, he found himself unable to part ways with the guide. To make matters worse, North was kept in the dark about the issue, and attended the premiere expecting to hear his hard work set to Kubrick’s masterful vision—sitting through all 161 minutes, only to learn that his score was abandoned in full, must have been demoralizing to say the least. Mondo Creative Director, Justin Ishmael sheds some light on the importance of the release, 'Alex North's Music For 2001: A Space Odyssey is beyond just an important piece of musical history, it is one of the best 'what ifs' in cinema history."
The site has some clips. The second one is for the space station docking sequence. It's interesting but I think Kubrick's choice is better, juxtaposing something old and something new made space travel more relatable. Still that could just be my bias for something that's now very familiar.
