Star Wars: Episode III : The Soundtrack

Using the vehicle of John Williams' music, Lucasfilm has provided an informative timeline for those needing help following the major themes of the saga. Actor Ian McDiarmid, (the evil Emperor Palpatine), provides an introduction for each of the 16 musical chapters. For example, in Chapter Two, "Dark Forces Conspire," he introduces the Galactic Republic, its protectors, the Jedi, and then their enemy, the Sith. Then comes a flurry of film clips set to Williams' music illustrating, in this case, the role of the Jedi and the conflict that will envelop the main characters. Source: TheState
