Acrimony was a Welsh stoner metal band who were active during the 1990s. Although the band never achieved mainstream success, during its career it received much critical acclaim and developed a cult following in the British underground metal scene. The All Music Guide described their musical style as "typical mid-'90s stoner rock" that "combined Black Sabbath's heavy metal riffery, Hawkwind's space rock excursions, and Blue Cheer's fuzzed-out psychedelic feedback with extreme doses of volume ... particularly reminiscent of desert metal gods Kyuss."
