Relationship of Command is the third studio album by American post-hardcore band At the Drive-In, released on September 12, 2000.

The album combines an aggressive edge with a melodic drive, harmonious, emotive vocals, and surreal lyrics.

Relationship of Command was recorded over a seven-week period starting on January 17, 2000,[6] following a tour supporting Rage Against the Machine.

The album was recorded at the Indigo Ranch Studios, in Malibu, California, and was produced by Ross Robinson and mixed by Andy Wallace.

Known for his unorthodox production methods, Robinson at one point took bass player Paul Hinojos for a drive in his SUV through the hills of Malibu to get his adrenaline going prior to recording.

"[7] In 2010, Rodriguez stated that he felt the album was “ruined by the mix”, calling it “plastic” and said he did not feel it captured the band’s true energy.

[28] A retrospective BBC music review hailed the significance of Relationship of Command's uniqueness, calling the album "mesmerising" and a "statement of grand intent that could never be followed.

However, despite this success, the band went on an indefinite hiatus in 2001, with the members splitting to form The Mars Volta and Sparta.
