Acid Bath is an American sludge metal band from Houma, Louisiana that was active from 1991 to 1997.

Acid Bath formed in 1991.[4] The band was based south of New Orleans in several small towns including Houma, Thibodaux, Morgan City, and Galliano.[4] Acid Bath was an incarnation of two bands,[4] Dark Karnival which featured Audie Pitre, Sammy Pierre Duet, and Tommy Viator, and Golgotha which featured Dax Riggs, Mike Sanchez, Jimmy Kyle, and Jerry "Boon" Businelli. Golgotha's bassists were in frequent rotation finally culminating with Chad Pierce, who would then be succeeded by Pitre during Acid Bath's formation. Tommy Viator was later replaced by Jimmy Kyle on drums but would return to play keyboards toward the end of the band's career. Joseph J. Fontenot was the bassist for a short period of time.

Influenced by thrash metal as well as bands and artists such as Black Sabbath, Alice Cooper, Celtic Frost, Carcass, and Darkthrone,[4] Acid Bath recorded their demo Hymns of the Needle Freak with their manager and producer Keith Falgout in 1993. The strength of the demo earned them a deal. They released When the Kite String Pops produced by Spike Cassidy in 1994,[5] followed two years later by their second and final effort Paegan Terrorism Tactics (also produced by Keith Falgout).[6] Neither gained them mainstream success, but both albums earned a high degree of underground acclaim. In 2005, another album composed of their demos, Demos: 1993–1996, was released.

The last show Acid Bath ever performed took place at the Shreveport Municipal Auditorium on April 25, 1997. Crowbar, Floodgate, and Dead Industry were also on the bill that night. Jeromy Boullion played guitar for Acid Bath instead of Mike Sanchez. Acid Bath didn't get paid because the show wasn't promoted properly and not enough people showed.[
