[3] Unpersons began touring in 2000 and released a self-titled debut extended play through the Fish Fur and Born to Die record labels that December.
[1] Unpersons released music through independent record labels in the 2000s and toured frequently, performing alongside bands such as Baroness,[5] Black Cobra,[6] Kylesa,[7] and Weedeater.
[13] Eduardo Rivadavia of AllMusic described Unpersons' style as a "gonzo brand of post-Jesus Lizard noise rock, topped with drunken, slurred vocals.
's Chris Gramlich said that "Unpersons are a gritty, dirty musical plague ravaging the listener,"[14] and called the band's sound "abrasive noise that recall the time when the Jesus Lizard were gods, but heavier, mixed with more aggression..."[15] Last Rites writer Chris Chellis said, "I hear traces of everything from hardcore, stoner, doom and sludge in [Unpersons'] sound, with the latter being the most dominant of those four.
"[16] Erik Thomas from Teeth of the Divine said the band's music was "experimental yet rooted in traditional stoner/sludge metal," with "furious drumming amid [an] off beat, angular, staggering, almost Mastodon-ish (and Kylesa) take on stoner rock."
