2000's swansong Relationship of Command follows on April 22 via Transgressive Records in digital and CD versions complete with bonus track 'Catacombs'.
It also gets a limited coloured vinyl release on April 20 for Record Store Day.
Guitarist and founding member Jim Ward said: "It was interesting to revisit the recordings that bookended the first chapters of our band.
"The earnest and pure excitement of the beginning and the level of craftsmanship we achieved by Relationship of Command leaves me nothing but proud.
"I am happy these records have found their way to continue to feel new as people discover music they love and embrace our work."
At the Drive-In confirmed their live reunion in January 2012 after an 11-year hiatus.
The band played several shows, including the Coachella and Reading/Leeds festivals and a one-off date at London's Brixton Academy.
Guitarist Omar Rodriguez-Lopez said following the reunion that the band do not have plans to record any new material, describing the comeback as "more of a nostalgia thing".
Cedric Bixler-Zavala last week confirmed that The Mars Volta, who formed in 2001 when At the Drive-In initially split, had broken up, citing Rodriguez-Lopez's lack of desire to tour.
