A longtime fan of David Bowie, Reznor has cited Bowie's 1977 album "Low" as one of his favorite albums and stated that he listened to it constantly during the recording of "The Downward Spiral" for inspiration. In 1995, Nine Inch Nails toured as a co-headlining act on the North American leg of Bowie's 1995 Outside Tour. Reznor also appeared in Bowie's video for "I'm Afraid of Americans" as Bowie's stalker, and made several remixes for the single release of the song (as well as a remix of "The Hearts Filthy Lesson"). The two came to consider each other friends. Reznor stated in the 2010 documentary "" that Rush had played a major part in his childhood influences. He said that he considered Rush to be "one of the best bands ever" and had gained a perspective on how keyboards could be introduced into hard rock after listening to their 1982 album "Signals". He also once said that "Freddie Mercury's death meant more to than John Lennon's", and he covered Queen's "Get Down Make Love" in 1990, which was co-produced by Ministry frontman Al Jourgensen and released on the single for "Sin".
