of Inner Turbulence", which makes up the entire second CD (albeit split into eight separate tracks), is the longest song Dream Theater have recorded to date. While recording, they wanted to keep the song at 20 minutes, but more and more ideas came which resulted in the length doubling. Realizing that they would have to cut "Disappear" and "Misunderstood" to keep the album at one CD, their record label was now open for the idea of a double album, something the band had previously been denied when recording Falling into Infinity for former label EastWest. Despite this, the cassette edition reduced "Misunderstood" to its radio edit version and omitted "Disappear" entirely. The last chord of "Six Degrees of Inner Turbulence" is used to open "As I Am" on the next album Train of Thought, continuing a chain which ended with Octavarium. Influences Influences for the album's writing and recording, according to the authors, include Metallica's Master of Puppets, Radiohead's OK Computer (and also a Radiohead bootleg Portnoy brought in), Pantera's Far Beyond Driven and the song "Mouth for War", Megadeth's Rust in Peace, U2's Achtung Baby, Tool's Ænima, Nine Inch Nails' The Downward Spiral, Soundgarden's Superunknown, Alice in Chains' Dirt, Kevin Gilbert's Thud, King's X's Faith Hope Love and Galactic Cowboys' Space in Your Face, Béla Bartók, Rage Against the Machine's The Battle of Los Angeles, and Maria Tipo's Chopin Nocturnes.
