- Creative Differences: The primary reason the band broke up. Cedric and Omar wanted their next album to sound like The Piper at the Gates of Dawn (notably, the band covered "Take Up Thy Stethoscope and Walk" around this time), while the rest of the band wanted to go in a more straightforward, stripped-down direction. This becomes even more evident when one compares the work of The Mars Volta to the work of Sparta. However that hasn't stopped them from doing sporadic reunions and finally reuniting completely in 2016.
- Creator Backlash: Omar isn't fond of the mix on Relationship of Command. While he respects Andy Wallace as a mixing engineer, he felt the album was a lot more energetic and raw when it was recorded, and says, "It's the one record I still to this day cannot listen to". Despite this, he also called "Non-Zero Possibility" "the best thing we ever did", making it a case of Creator Backlash and Creator's Favorite Episode at the same time.
- Cedric has also gone on to say he isn't terribly fond of the record saying that he felt it was kind of stagnant in comparison to their earlier records. He also reckons that he doesn't remember much of the tour.
