There is a rather dark,haunting,powerful,bombastic,dissonant theme for the siths (namely,for Darth Maul)which sung in the sith language.There is a complex theme for Anakin,which is rather dark and sad,but not without its brighter moments:dark to illustrate the troubles of the young boy,and to illustrate that there is a certain amount of evil in him,and to reflect to his unhappy life as being a slave.It further illustrates that he cannot put his dreams into reality because the circumstances made it impossible.There are extremely powerful,exciting and bombastic action tracks which are brass-driven,further accompanied by strings.There are some playful and relaxing cues as well,and and extremely effective and well-performed funeral theme with a hearth-breakingly sad choir.
Worth to check out.
