 Also in 2004, the band recorded the song "SpongeBob and Patrick Confront the Psychic Wall of Energy" for the soundtrack of "The SpongeBob SquarePants Movie".Following the concerts' cancellation, the band entered Tarbox Road Studio with producer Dave Fridmann and began work on their eleventh album, the more organic-sounding "At War with the Mystics".The record, aimed to be a more guitar-based and heavier effort than recent albums, featured more politically conscious lyrics than any of their previous releases, and was released in April 2006 to a mixed yet mostly positive reception.
