Soilent Green was founded in 1988, but their debut album was not released until 1995, when Pussysoul came out via Dwell Records.
[3] Soilent Green's musical style is characterized as a mixture of grindcore with sludge and blues-heavy southern rock.
[4] Rock Hard initially saw the band as an intersection of Eyehategod, Crowbar and Anal Cunt with occasional borrowings from death metal,[5] but on the next album the group's sound focussed on grindcore, which the band combined with influences from sludge and technical death metal,[6] and coined the term "sludgegrind" for Soilent Green's 2008 album.
[7] Michael Edele of laut.de described the band's style as a "contradictory mixture of hardcore, sludge, grindcore and southern rock".
[10] In 2009, Soilent Green was featured on the first episode of season four on the Adult Swim show Squidbillies, entitled "Lerm".
