Stanley Kubrick was one of the greatest moviemakers of all time. But he also had an excellent ear for music, as shown in 2001: A Space Odyssey. From the dramatic strings of Also Sprach Zarathustra, which the movie is unthinkable without, to the waltzes of Strauss's The Blue Danube, this is an excellent soundtrack.
First off, almost all the music is excellent. Like I said, Kubrick knew good music. Second, the tracks are presented beautifully and sound clearly. I had to spend some time adjusting the volume so I wouldn't get complaints from the neighbors. The CD also comes packaged with an excellent booklet that tells about the movie and some of its themes and about the music. There is also some interesting trivia (Did you know Gyorgy Ligeti sued Kubrick for altering his music without permission?).
While overall excellent, everything in life has flaws and this is no exception. "Requiem", for example, is not long but rather surreal. It seems to foreshadow the apocalypse more than space travel. The Overture is also surreal, though not as long. "The Stargate" is the longest on the soundtrack, combined with three tracks. But what may be the worst music on the CD is the unaltered "Adventures", if it can be called music. It sounded to me more like a guy laughing wickedly as he bangs on a piano while a woman moans as if in the act of sexual intercourse. It's no wonder Kubrick altered it for the movie (Another example of his ear for music). One other complaint, though minor, is how the Blue Danube is split into two tracks.
The next reissue, if there is one, should get rid of "Adventures" and bring the complete "Blue Danube". Otherwise, enjoy!
