Train of Thought is the seventh studio album by American progressive metal band Dream Theater, released on November 11, 2003, through Elektra Records. The album's length is 69:21. Dream Theater decided to take a much heavier approach to this record because of the audience response to their heavier songs while they were on tour. This resulted in some of the most impressive heavier progressive metal in the genre. The band includes lyrical themes of religion, family issues, and alcoholism.

Six Degrees of Inner Turbulence began a trend towards insane instrumentation and darker themes in Dream Theater's music that is continued and taken to another level on this record. Train of Thought is not only great for the progressive music fans, but also for those who are fans of heavy metal. The ridiculous amount of flamboyant instrumentation combined with darker tones and themes make this album one of the most memorable in the entire Dream Theater discography.

The album’s main standout track that I think best represents what the band wanted to go for with this record is the song “As I Am.” This is one of the band’s heaviest tracks that has a crushing riff, memorable chorus, and an insanely fast face melting guitar solo. John Petrucci may show off his prowess a bit too much on this song for some, but I happen to absolutely love it. This is just one of many classics that the album has to offer.

Train of Thought is such a well put together album that shows off all of Dream Theater's strengths in songwriting, instrumentation and conveying emotion through their lyrics and music. Despite the additional emphasis on utilizing a heavier sound, Dream Theater did not lose the characteristics that make them who they are, while adding a darker element that allowed them to expand and improve their sound. Even by Dream Theater standards, this album is very impressive and is a progressive metal classic.

Rating: 4.5/5
