I Worship Chaos is the ninth studio album by Finnish melodic death metal band Children of Bodom. It was released on October 2, 2015. It is the first album since 2003's Hate Crew Deathroll not to feature guitarist Roope Latvala due to his departure from the band in May 2015, making this the band's first album as a four-piece group with Alexi Laiho handling all guitar duties. For the first time, the band did not use a commercial recording studio. Instead they opted to use a converted warehouse to enhance the ambiance of the sound.
