During the early to mid-'90s, Bates scored a number of B-movies. In the meantime, he was part of the alternative rock band Pet, along with vocalist Lisa Papineau
. Pet's 1996 eponymous album debut was executive produced by Tori Amos
and released on her Atlantic Records
vanity label Igloo
. The band was featured on the soundtrack albums The Crow: City of Angels (1996) and The Last Time I Committed Suicide (1997). Bates left Pet in 1997 and began concentrating on film, composing full-time following the success of The Last Time I Committed Suicide, which he scored.
He had steady work thereafter, including the films Get Carter (2000), City of Ghosts (2002), and Dawn of the Dead (2004). Bates subsequently worked with rocker-turned-director Rob Zombie
on several of his films, including The Devil's Rejects (2005), Halloween (2007), and Halloween II (2009). Besides horror film work, he carved out a niche for himself in the science fiction field, composing music for the films Slither (2006), The Day the Earth Stood Still (2008), and Watchmen (2009). Outside the realm of film, he worked on the celebrated television series Californication and composed music for video games as well.
In 2015, Bates also joined Marilyn Manson
's touring band as guitarist after producing and co-writing their 2014 LP The Pale Emperor. "Cupid Carries a Gun" from the album was used as the opening title music of the supernatural TV drama Salem, which Bates also scored. Other highlights from this period included the Jason Momoa reboot of Conan the Barbarian (2011), the Guardians of the Galaxy saga (2014 and 2017), and the John Wick series (2014 and 2017), both of which were co-written with Joel Richard. Later, he collaborated with Wick's co-director David Leitch on both the soundtrack to his 2017 film, Atomic Blonde (which featured covers and originals of '80s hits, as well as a Bates/Manson collaboration on the Ministry
cover "Stigmata"), and 2018's Deadpool 2. ~ Jason Birchmeier, Rovi
