Recording

The album was recorded at O'Henry Studios in Burbank, California, as well as at The Loft and Grandmaster Studios in Hollywood, California. It was mixed at Bay 7 in North Hollywood, CA and mastered at Gateway Mastering Studios in Portland, Maine. The June 2006 issue of Guitar World (released April 11, 2006) featured an interview with guitarist Adam Jones discussing the new album. Jones explained that recording techniques for the album involved the use of a "pipe bomb microphone" (a guitar pickup mounted inside a brass cylinder), and a talk box guitar solo on the song "Jambi". The "pipe bomb microphone" and other studio related information was further detailed in the June 1, 2006 issue of Mix. Drummer Danny Carey operated many of the sound effects on the interlude tracks on the album using electronic drums called Mandalas.
