In January 2013, Reznor appeared in a documentary entitled "Sound City", directed by former Nirvana drummer and Foo Fighters frontman Dave Grohl. "Sound City" is based on real-life recording studio Sound City Studios, originating in Van Nuys, California. It has housed the works of some of the most famed names in music history since its founding in 1969. The film was chosen as an official selection for the 2013 Sundance Film Festival and was available to download from its official website on February 1, 2013. Reznor also contributed to the soundtrack for the film, on the track "Mantra", along with Dave Grohl and Josh Homme.
