composed theme for Call of Duty

In July 2012 Reznor teamed up with video game developer Treyarch to compose the theme music for Call of Duty: Black Ops II . Later that year Reznor again worked with Atticus Ross along with Alessandro Cortini on a remix of the song “Destroyer” by Telepathe . Reznor also appeared in a documentary called ” Sound City ” directed by Dave Grohl , in addition to co-writing and performing the song ” Mantra ” with Grohl and Josh Homme . This led to further collaboration with Reznor and Homme on the 2013 album from Queens of the Stone Age titled …Like Clockwork . Reznor contributed vocals and drum programing to the song “Kalopsia” and vocals on “Fairweather Friends” along with Elton John on piano and vocals. In October a project with Dr. Dre and Beats Electronics was announced that Reznor wrote was “probably not what you’re expecting [from me]”. The project was named “Daisy”; a digital music service was announced in January 2013. It was until January 2014 that the service was fully launched, with Reznor serving as chief creative officer.
