During his October 4 concert in Milwaukee, and as an introduction to his performance of The Throne Room and End Title from Star Wars, John Williams revealed that “in about two weeks” he would start working on the score to Star Wars: Episode VII. The new chapter in the Star Wars saga is scheduled for release on December 18, 2015. – Read the original report at MakingStarWars.net
UPDATE: According to an UNCONFIRMED RUMOR (posted by record producer Ford A. Thaxton on FSM), the reason Williams will start working on Star Wars: Episode VII this month might be because Disney wants to release the first teaser for the film on Christmas Day. The teaser would feature original music written by Williams and recorded in Los Angeles.
