The music of “Destiny” was a collaborative effort between Bungie's former in-house composer Marty O'Donnell, his partner Mike Salvatori and former Beatle, Sir Paul McCartney.
The New York Times reports that one of McCartney's contributions to the game's soundtrack, "The Hope Song" will be released as a single.
The Times calls McCartney's track the game's theme song, reporting that it is fully orchestrated and was recorded at Abbey Road Studios under the direction of Giles Martin, son of The Beatles producer Sir George Martin.
The song's producer is Mark "Spike" Stent, who has experience recording a handful of James Bond movie theme songs: Tina Turner's "GoldenEye" and Madonna's "Die Another Day."
McCartney announced his involvement in the Destiny score in 2012, tweeting, "I'm really excited to be working on writing music with @bungie, the studio that made Halo."
O'Donnell detailed his collaboration with McCartney last year when Bungie unveiled the first details on Destiny. He said the former Beatle was drawn to the project by his interest in the technology behind interactive music. "He didn't only want to do Paul McCartney music," O'Donnell said. "He wants to get involved in themes, how melodies and motives can be a touch point for people."
