This CD contains, inter alia, more instrumental soundtrack from Part 1 as the official CD, which offered in addition to the great issue only one suite (Letter / Clock Tower Part 1 / Doc lives). Here you can hear for the first time the complete music for one of the most exciting highlights of film history (a highlight without dead and fight)! Clock Tower Part 2 is a rousing piece, which was recorded by the great RSNO and never listen to a LP or CD beforehand was !!!. The original is a little faster, but here the orchestra is bigger and more powerful. Also new is the music to skateboarding scene and the music to the scene where Marty arrives too late in 1985 and must see that Doc is shot again. A track, which is also available on any of the original official CDs on it, is the piece "The West" - the Music of Trailers of Back to the Future. 3 Even if you should have all 3 original CD's, so, this CD is a great addition!
