100 Demons is a five-piece metalcore band from Waterbury, Connecticut. Being fans of tattoos, the band derived their name from a book of traditional Japanese tattoo artwork by Horiyoshi III. The band often incorporates their Agnostic beliefs into their lyrics. 
After over a decade of playing in the Connecticut hardcore scene, Deathwish Inc. announced the signing of 100 Demons to a record contract in 2003. In a press release the label was quoted as saying “Today’s 100 DEMONS encapsulate a viciousness and ravenous intensity that few could achieve.” The band then found themselves at Planet Z Studios with producer Zeuss (Hatebreed, Shadows Fall) recording their self-titled album.
Their video for “Repeat Process” was featured on Headbangers Ball.
