Psychic Ills were formed in 2003 by Tom Gluibizzi (guitar/keyboards) and Tres Warren (vocals). The band issued two limited-run vinyl recordings (Mental Violence I in 2004 and Mental Violence II in 2005), both of which Social Registry reissued together as Early Violence, adding two extra songs. Following Mental Violence I, the duo was joined by Elizabeth Hart (bass) and Brian Tamborello (drums). Psychic Ills, who have opened for the equally psychedelic Warlocks, released their first proper full-length, Dins, in February 2006. The largely improvised Mirror Eye arrived in 2009. For 2011's Hazed Dream, the band moved to Sacred Bones and opted for a more streamlined, accessible approach. 2013's One Track Mind continued on into even more accessible territory, with production and guest vocals from Royal Trux's Neil Michael Hagerty. Brent Cordero, who had played keyboards with Psychic Ills on tour, became part of their studio crew for the sessions that produced the group's fifth album, 2016's Inner Journey Out. The album also featured a guest appearance from Hope Sandoval of Mazzy Star, who contributed vocals to the song "I Don't Mind."
