Tomoya Ohtani on Sonic Lost World Original Soundtrack:

The Deadly Six Theme (Orchestra ver.)

They are battles with Deadly Six for two times in one world, but this music is used in the world’s final battles and is the orchestra arrangement of The Deadly Six Theme. Mr. Eguchi thought of the orchestration with the direction of showing the intensity without altering the original’s composition, image, and others for the orchestra arrangement. Of course, the orchestra is a live recording.
