When the news broke that Disney would be producing a new trilogy of "Star Wars" films taking place after the events of "Return of the Jedi," the logical choice was to have John Williams return to continue his expansive space opera composition. And he returned with some new themes for "The Force Awakens" that featured a complex motif for the female hero and a theme for the villain that, not surprisingly, had a connection to Vader's theme. Host Jeff Commings is joined by Paulius Eidukas for an examination of Williams' compositional techniques for the new film, and why some music might have a connection to the Harry Potter scores.
