More details have emerged about Paul McCartney composing music for a video game. The game is called Destiny and Macca has been working on the soundtrack with Marty O'Donnell, who has worked on the Halo franchise's previous soundtracks. They have been working on and off on the project for two years with O'Donnell saying, "He didn't only want to do Paul McCartney music. He wants to get involved in themes, how melodies and motives can be a touchpoint for people." Some of the loops that McCartney created for the game were done on the same machine The Beatles used to make loops on Revolver.
