In an interview with Ultimate Metal.com, Jeff said that "The Habit of Fire is a concept album about the living energy in a human being that has become our archetype of survival......The fire itself represents an energy or spirit that can never be taken down by outside forces. The lyrical themes are based around a 12-million people metropolis within a post-dictatorship country, heading down into chaos due to the people's inability to adapt with the global winds of change."
Recording
In the same interview, Jeff said that the recording process was only the second album that the band did not have a single problem in the recording process. About 75% of the music was written during pre-production. Jeff would collect samples and create MIDI information, and manipulate the sounds to create the 'skeleton'. Then riffs, MIDI instruments, synthesizers, and melodies would be added and the structure re-arranged. Once the song structure was set, the guitars would be re-recorded, then bass and drum tracks would be put on top, then vocals. Overall, it took over seven months to complete.
Reception and style
The Habit of Fire met with a mixed reception by critics. It was praised for its diverse style and instrumentation as well as its quality musicianship, but was considered repetitive and over-indulgent at times, as well as somewhat inaccessible and difficult to digest. The album was nominated for The BestAvantgarde Metal Album award by the popular metal website Metal Storm, and on November 2007, the album was chosen as the CD of the Month by UK's music technology magazine Sound on Sound. On this release, the band reduced its black metal sound to make room for atmospheric soundscapes and industrial textures. The music is varied, combining the band's metal roots with styles such as progressive rock, electronica, psychedelic ambient, and jazz fusion, giving the album a "breathless, almost ADD" feel. The experimental aspects of the album were likened to Tool, while the progressive elements were compared to Marillion and the heavier passages to Mortal. PopMatters described the album as "flipping randomly between radio stations playing Rush, King Crimson, Ulver, and the Mars Volta".
