soundtrack?

Rating: Null/10 (7 November 2004)

awesome movie...one of the best and intellectual of all of A.C.C's works. a few questions... firstly, why were the others.. the remaining sections of the story never made? 2010: Odyssey 2, odyssey 3 and 3001 the final odyssey?
i started to read the other books at college, but they are pretty heavy going if you didn't understand the movie, or have forgotten what it is about.
directed by Stanley Kubrick? when i saw this, i thought ' well, a film he's made that isn't....odd'
and one more thing: i can't find who wrote/ performed the music from the movie.. who composed/performed it, and where could i get the soundtrack?
