Any of Bernard Hermann's film scores, Glory, Patton, Willow , The Right Stuff. Victory At Sea by Richard Rogers for the TV series. I liked Dimitri Tiomkin's westerns. Morriconi ( wrong spelling) for Eastwood's spaghetti westerns. Virgil Thomson's " The River" and "The Plow That Broke The Plains" Some of these are old but still good.
Best Orchestral Film Scores
I enjoy orchestral works for film. Two good examples are Gladiator by Hans Zimmer and Lisa Gerrard and Empire of the Son by John Williams. John Williams seems to have a very impressive body of work. Who are your favorite modern day orchestral composers and what film scores have they done that you like.
