Re: John Williams to Score Star Wars Episode VII
The best tracks Williams did for Star Wars were copied almost beat for beat from Mussorgsky and other composers. George Lucas discussed in a few interviews over the years how he would write scenes to music then get John Williams to compose a track that evoked the same emotions. e.g. Duel of the Fates is just a remix of O Fortuna by Carl Orff.
If Abrams uses the same technique to score his film any composer will do.
