Six Degrees of Inner Turbulence

Six Degrees of Inner Turbulence (often abbreviated to SDOIT or 6DOIT) is the sixth full-length studio album by progressive metal band Dream Theater. It was released on January 29, 2002 by Elektra Records.




History
Fans’ reactions to the album were mixed, with many pointing to the obvious differences between the two CDs as two different types of Dream Theater style. The first disc is generally seen as experimental and heavy while the second disc is seen to be more in line with the previous Scenes from a Memory.

Songs
The first track of the first disc begins with the white noise that ended Scenes from a Memory, while the last track, Losing Time/Grand Finale ends with a long chord played by (synthesized) strings, which was also used as the intro to their next studio album, Train of Thought.
The entire second disc is occupied by the 42-minute title song broken into 8 tracks.
The first track of the album, “The Glass Prison,” tells Mike Portnoy’s story of rehabilitation from alcoholism. “The Glass Prison” is composed of three parts and Portnoy intends to extend the song into twelve parts that mirror the twelve steps of the AA program by Bill W. for rehabilitation of alcoholics. This song is continued in tracks on the next albums (“This Dying Soul” on Train of Thought, “The Root of All Evil” on Octavarium and “Repentance” on Systematic Chaos).
The Great Debate is a non-partisan song dealing with the topic of stem-cell research.
