Muse's third album was recorded in lots of studios in places like London and Los Angeles. The band were very committed and focused on making quality music, given the fact that they had taken more time to properly record the album. Muse started work in September 2003 with producers Paul Reeve and John Cornfield, and recorded Butterflies and Hurricanes and Blackout. They took a break for Christmas, and then changed their producer to Rich Costey. Most of the album was recorded in 2004. The album's themes included politics, death, and the Apocalypse. The guitar performances on the new album were simpler than on "Origin of Symmetry". Bellamy used one brand of guitar for the whole album, and this gave an "immense" sound according to "Total Guitar" magazine.
