The band's music is heavily influenced by the late 1960s when
heavy metal was emerging.
AllMusic praised the band's ability to recreate a particular aspect of this era, describing the band as "celebrating the
Summer of Love's soul-chilling autumn: a blasted landscape, post-
flower power, resembling
Altamont's killing fields, reeking of the
Manson Family murders, and, naturally, sounding like a mish-mash of all of the apocalyptic musical forces that converged upon that era". Their record label,
Metal Blade Records, described the band as "the original
Alice Cooper band jamming in a cell with early
Black Sabbath and
the Stooges". In order to replicate the sound of that era, the band uses vintage instruments and recording equipment. The band's name was taken from
Rusty Day, the singer of
Cactus, who later had a band called Uncle Acid and the Permanent Damage Band. Uncle Acid was originally the otherwise-anonymous frontman, although he has since changed his stage name to K.R. Starrs and now views the band members collectively as being "Uncle Acid".
Blood Lust was the band's breakthrough album, with
The Quietus describing it as "a glorious and idiosyncratic collection that quickly garnered rabid cult status amongst the worldwide doom fraternity"
AllMusic described
Blood Lust as "a mixture of psychedelic rock's harrowing comedown, garage and punk rock's nihilistic ascent, and the earliest manifestations of heavy metal's
occult-laced, nerve-damaging bludgeon". With the release of the band's third album,
Mind Control, more 1970s pop influences were incorporated into the music. A concept album, K.R. Starrs explained that
Mind Control is a "fictional story ... about a cult leader who comes down from the mountain and brainwashes his desert disciples through drugs, love, violence, and intimidation". According to
Metacritic, the album has received "universal acclaim" with a score of 81 based on seven critics. Justin Norton, writing for
Decibel Magazine, awarded the album a score of eight out of 10 and described the album as "a perfect union of
Sabbath riffs, fuzz and
Herschell Gordon Lewis". They are confirmed to be performing at the
Hellfest music festival taking place in
Clisson in June 2026. ==Band members==
