McCartney has been working with Bungie and its recently fired composer Marty O'Donnell on Destiny's soundtrack, on and off, since 2010. If you've played the beta, then you've already heard a portion of their work, but according to the Times, McCartney recently decided to collaborate on a theme song for the game.
The song, which we don't have a title for yet, was recorded at the famous Abbey Road Studios with a 120-piece ensemble. It was produced by Mark Stent, who previously worked with artists like Madonna, Bjork, and Lady Gaga. According to the Times, the song is about hope.
Previously, McCartney only mentioned his collaboration with O'Donnell and Bungie once, in a tweet. “I’m really excited to be working on writing music with @bungie, the studio that made Halo,” he said.
The single will release "soon" after the game launches.
O'Donnell, who worked at Bungie for more than a decade and composed Halo's iconic theme song, was fired in April, "without cause," he claimed. O'Donnell has since filed a lawsuit against Bungie, but settled out of court for $95,000.
