Daniel Davies was born in London and spent much of his childhood on the road with his father's band as it toured the globe. His family moved to Los Angeles when he was 11, and after his parents split up, Davies lived with Carpenter during part of his adolescence. He learned to play guitar and drums as a high school student, and appeared on the soundtrack to Carpenter's 1998 film, Vampires. In 2003, Davies befriended Rich Mullins, bassist of the desert rock band Karma to Burn. Following a jam session with Third Eye Blind drummer Brad Hargreaves, the trio formed Year Long Disaster in 2004. With influences ranging from ZZ Top to Iron Maiden, the group built up a local following and signed to Volcom Entertainment in 2007, releasing their self-titled debut that year. They soon toured with Clutch, Turbonegro, and Motörhead, and released their second album, Black Magic; All Mysteries Revealed, in 2010. Also that year, Karma to Burn reunited and toured with Year Long Disaster before the two bands ultimately merged. While Karma to Burn were normally known as an instrumental band, Davies sang on the few vocal-based songs on the band's albums Appalachian Incantation (2010) and V (2011).
Hidden Faces, Davies' self-released solo EP of moody, slightly proggy alternative rock songs, also appeared in 2011. Following its release, Davies briefly joined CKY, replacing former frontman Deron Miller. Davies toured with the group in 2012 and returned for a 2015 performance, and had begun to record new material with them but was unable to continue participating in CKY due to other commitments. Along with Geno Lenardo, he recorded much of the soundtrack for the 2014 film I, Frankenstein, and co-composed the score for 2015 horror-comedy Condemned with Sebastian Robertson. He also recorded music for several TV series and films, including a cover of Pixies' "Wave of Mutilation" for Sharknado 3: Oh Hell No!
Most notably, Davies worked with John Carpenter and his son Cody. The trio recorded Lost Themes, the director's first album of non-soundtrack material, which was released by Sacred Bones in 2015. The effort received critical acclaim and was followed by Lost Themes II in 2016. The trio toured behind the releases, marking Carpenter's first-ever live performances, and they revisited some of the director's signature tunes on 2017's Anthology (Movie Themes 1974-1998). In 2018, Davies released his first solo full-length, Events Score. As with the Lost Themes releases, the album isn't a soundtrack to an actual film, but it evokes the synth-driven scores of the '70s and '80s. His second solo album, Signals, was inspired by visual artist Jesse Draxler, who provided artwork for the release's cover and booklet. Sacred Bones issued Signals in 2020. Davies' Spies EP, recorded entirely solo during COVID-19 lockdown, appeared in 2021. That year, he also worked with John and Cody Carpenter on the score for Halloween Kills, which updated the legendary horror franchise's iconic music with an expanded sonic palette. ~ Paul Simpson, Rovi
