At the Drive-In was an American post-hardcore band from El Paso, Texas, formed in 1994. The band's most recent line-up consisted of Cedric Bixler-Zavala (vocals), Omar Rodríguez-López (guitar, vocals), Paul Hinojos (bass), Tony Hajjar (drums) and Keeley Davis (guitar, vocals). After several early line-up changes, the band solidified into a five-piece, consisting of Bixler-Zavala, Rodríguez-López, Jim Ward (guitar, keyboards, vocals), Hinojos and Hajjar.

At the Drive-In released three studio albums and five EPs before breaking up in 2001. Their third and final album before the split, 2000's Relationship of Command, received a number of accolades and is cited as a landmark of post-hardcore, alongside producing the successful single "One Armed Scissor". Following the breakup, Bixler-Zavala and Rodríguez-López formed the Mars Volta while Ward, Hinojos, and Hajjar formed Sparta; Hinojos would later join the Mars Volta.

At the Drive-In reunited in January 2012 and played the 2012 Coachella Valley Music and Arts Festival, as well as the 2012 Lollapalooza Festival. In 2016, the band reunited for a second time, with Ward replaced by Sparta's Keeley Davis; they released the album in•ter a•li•a the following year. The band announced an indefinite hiatus in November 2018.

At the Drive-In was founded in 1994 in El Paso, Texas, by guitarist Jim Ward and vocalist Cedric Bixler-Zavala. The band played its first live show on October 14, 1994, at The Attic in El Paso, followed by a show on the 15th at the Loretto High School Fair. They released the EP Hell Paso in November 1994. Following Hell Paso's release, the band members embarked on their first tour – a 2,000-mile trek across Texas. After a drummer change due to Bernie Rincon's death, At the Drive-In released its second EP ¡Alfaro Vive, Carajo! in June 1995. The band then set out on another tour, this one in a newly purchased 1981 Ford Econoline and spanning 42 days and 10,000 miles across the United States. During these tours, At the Drive-In began developing a large underground following by mostly playing in basements and small venues across the western United States, with their popularity spread by word of mouth among fans. One such show that changed the course of history for the band was in a now defunct bar in Los Angeles, where the band put on an explosive performance for just nine people – some of them employees of the Flipside record label. The staffers were so enthralled by the show that they offered to put out At the Drive-In's debut album then and there. After accepting the offer, the band first headed out on another 21-day tour of the Southwest; they then recorded Acrobatic Tenement in Los Angeles for $600.

The album was released on August 18, 1996; the band commenced another tour of the United States the following year, spanning 100 days (February to June 1997) and 24,000 miles. This tour included shows with hundreds of other bands such as Screw 32, J Church, AFI, Still Life, Mustard Plug, Face to Face, and Cosmic Psychos. At the Drive-In's fan base began to swell with every show it performed. Following this tour, the band members took a month's vacation before rehearsing for their next record and subsequent tour. Following the recording of Acrobatic Tenement in July 1996, the final line-up of At the Drive-In fell into place with the addition of Tony Hajjar and Paul Hinojos and with Omar Rodríguez-López moving from bass to guitar. The EP El Gran Orgo, which did not feature Ward, was released on September 18, 1997, and "showed a more melodic side of the band, but the musical depth and heartfelt emotion was never more apparent." Two days after its release, the band was in Boulder, Colorado, playing a show with Welt to kick off its next 35-day, 11,000-mile tour that also included six dates with Karp and the Young Pioneers, and one-offs with Guttermouth, the Criminals, Piss Drunks, and the Humpers.

By the time that the band were due to begin recording their second album, Flipside had stopped releasing new material and Offtime was financially unable to, "so the band figuratively approached almost every indie label they could think of" but could not find one willing to work with them. Eventually, Bob and Michelle Becker of Fearless Records saw At the Drive-In open for Supernova at a bar named Club Mesa. Despite Fearless's history of producing mainly pop punk bands, the band members "felt very comfortable with Bob and Michelle on a personal level" and a deal was signed. At the Drive-In began recording In/Casino/Out on June 3, 1998. With producer and mixer Alex Newport, the band spent four days recording at Doug Messenger's in North Hollywood and Revolver Recordings in Costa Mesa with engineer Andy Troy, and an additional two days mixing the album at Paramount in Hollywood. This album marked a notable maturation in At the Drive-In's sound and was recorded live with just a small number of overdubs. In/Casino/Out was chosen to be recorded live because, according to some sources, At the Drive-In struggled to capture the intensity and emotion of its live shows in the recording studio.

In/Casino/Out was released on August 18, 1998, although the band toured almost non-stop from July until December, playing shows with bands like Knapsack and The Murder City Devils. At the Drive-In took a couple month break until March 1999, at which point they kicked off another tour with a two-week stint with Jimmy Eat World in the United States until they headed to Europe for a six-week tour spanning eleven countries.

Upon returning to the United States, At the Drive-In played a handful of shows before returning to the studio to record the EP Vaya, which was released on July 13, 1999. The band then kicked off another tour on July 28 at Emo's in Austin, Texas.
