I was listening to The Score, a programme about film music on Oneword Radio, a UK digital station.
On June 24 they played both scores for Kubrick’s 2001: A Space Odyssey. I was unaware there were two scores but you may not be so ignorant. However if you are then it is a fact that Stanley Kubrick commissioned Alex North to write the score for his film 2001: A Space Odyssey, but decided against it in favour of the classics we know. North’s score is in two movements, reflecting the first and second chapters of the film.
‘The 2001: A Space Odyssey score is an unused film score composed by Alex North for Stanley Kubrick’s 1968 film, 2001: A Space Odyssey.’
‘North, unaware that Kubrick had decided not to use the score in his film was “devastated” at the 1968 New York City premiere screening of 2001 not to hear his work, and later offered this account of his experience:
“Well, what can I say? It was a great, frustrating experience, and despite the mixed reaction to the music, I think the Victorian approach with mid-European overtones was just not in keeping with the brilliant concept of Clarke and Kubrick.”‘
Wiki also indicates scholars and critics seem to have opposing views on which score is best.
Oneword’s Score programme on 24 June, played pieces from sci-fi soundtracks, as follows
1. Prelude & Outer Space - Bernard Herrmann; from The Day The Earth
2. Also Sprach Zarathustra - Richard Strauss; from 2001: A Space
3. Main Title - Alex North; from Alex North’s 2001.
4. The Blue Danube (excerpt) - Johann Strauss; from 2001: A Space
5. Space Station Docking - Alex North; from Alex North’s 2001.
6. Ontological Shock (excerpt) - Don Davis; from The Matrix.
7. The Artifact And Living - Michael Andrews; from Donnie Darko.
8. We Don’t Have To Think Like That Anymore - Cliff Martinez; from
9. Main Title - Jerry Goldsmith; from Alien.
10. Throne Room/End Title - John Williams; from Star Wars Episode IV: A
Unfortunately that programme will not be repeated (I have asked) and the music copyright prevents a downloadable ‘listen again’ version but you can find the music via the Score’s website.
