The album was finished in three weeks during the month of August 2008, in Brooklyn, New York. It's our version of what we consider an acoustic album." That's what our band does - celebrate mutations.

Rodriguez had discussed the band's next album (then untitled) as early as January 2008, the month that The Bedlam in Goliath was released, claiming "I consider it to be our acoustic album." Bixler-Zavala has also spoken of the album as "acoustic" and "mellow," yet stated: "We know how people can be so linear in their way of thinking, so when they hear the new album, they're going to say, 'This is not an acoustic album! There's electricity throughout it!' But it's our version. The song eventually ended up on Octahedron as "Since We've Been Wrong". Later, the song (unofficially named "Beneath the Eyelids" by the fans) was played live by the band at the New Year's Eve show in San Francisco at the end of the acoustic set, introduced by Cedric Bixler-Zavala as "the song that we worked on that hasn't come out yet". In October 2007, a 30-second clip of a new song was leaked onto the Internet, originally assumed to be from the upcoming The Bedlam in Goliath. Yet, as Bedlam turned into a "nightmare of a record to make", Rodriguez was unable to sustain both projects and devoted his attention on Bedlam.

Omar Rodríguez-López started working on Octahedron in 2007 at the same time as The Bedlam in Goliath, in his typical fashion of working on two or three projects simultaneously.
