The soundrack for 10,000 BC is not for everyone (but then, show me the soundtrack that is). It is much like Brian Tyler or Steve Jablonsky's work in that there is a great deal of complex percussion. There are also two beautiful themes: a melancholoy love theme, and a dramatic theme for what I assume would be wide vista shots. These themes are found primarily in tracks 4, 9, 14, 20, 21, and 22. My favourite is 22 by far, but I also love track 14 (sea of sand). There is also a good deal of 'ethnic' chanting.
Having never seen the movie, I am actually quite addicted to the tracks listed above. There is some similarity to King Arthur (Hans Zimmer) and there is this sweet 'David Bell Chord' in track 22 (but only a Trekkie would care about that). This is not my favourite CD but I've quickly developed a deep fondness for it. Some day, when I see the film I may appreciate more of it. This particular work caters to those who want themes and those who prefer a more atmospheric/percussive sound. I think it has the potential to impress many people.
