The Valiant Hearts: The Great War soundtrack uses a wide array of popular classical music. These are just some of the tracks that make up the game’s excellent score.
Hungarian Dance No. 5. Johannes Brahms
Infernal Galop, Offenbach
Night on a Bald Mountain (or: that dope song with the gargoyle in Fantastia), Mussorgsky
Flight of the Bumblebee, Rimsky-Korsakov
