Enigma Machine is the fourth track and second instrumental from Dream Theater's eponymous 12th studio album, Dream Theater. It marks their first full length instrumental on a studio album since Stream of Consciousness in 2003.
John Petrucci recorded this song using a 7-string guitar in standard tuning (B-E-A-D-G-B-E).
The title of the song refers to an electro-mechanical German cipher device used in WWII. The British set up the Bletchley park project to crack the code, which Alan Turing eventually achieved.
According to Petrucci, the theme surrounding the instrumental is a secret agent/spy music. This becomes evident in the atmospheric keyboard intro, and the driving main riff, both of which are reminiscent of James Bond movies, albeit heavier and more progressive.
