He was fired half a year before TDB came out.[/quote] Ahh the Internet. The source of truth Here is an excerpt from the article we are all talking about right now. [quote]Pete Parsons, chief operating officer of Bungie, asked O’Donnell to create all of the music for the entire Destiny franchise at the same time, rather than writing the themes one at a time for each of the game installments. O’Donnell composed a symphonic suite of eight movements, working with the legendary ex-Beatle Paul McCartney. O’Donnell recorded that music in early 2013. Dubbed the Music of the Spheres, the music will be used throughout the Destiny franchise.[/quote]
