The name "Xasthur" is a combination of "Hastur" and "Xenaoth". Conner explained that he found the former name in a Necronomicon paperback and believed that it referred to "a demoness who kills people in their sleep". The latter name referred to a celestial deity he read about in a book on the Afro-Caribbean religion Santería.^[1]

Xasthur was created in December 1995 in Alhambra, California, after Conner had played with several local death metal groups in Southern California.^[2] Initially, the band began rehearsing and recording in a home studio with an unstable lineup. A 10-track tape of these early rehearsals was circulated on the trade scene. While the original of that tape was destroyed, some tracks appeared on re-releases of later albums.

For a self-released split album with Orosius, Conner was joined on drums and vocals by friend Mike Pardi from the band Draconis, who used the stage name "Ritual." Subsequently, Xasthur became Conner's solo project, although Khaija "Blood Moon" Ausar (of Dacon and Crimson Moon) later appeared as a session musician on the song "A Curse for the Lifeless" (from Nortt/Xasthur) and the EP Xasthur, Mark "M.H." Hunter performed on Defective Epitaph and All Reflections Drained, and Marissa Nadler sang on Portal of Sorrow.

Before releasing their first official full-length album in 2002, Xasthur recordings were distributed in limited editions, which were later re-released by the Swedish Total Holocaust Records and other small underground labels.

The band's first album, Nocturnal Poisoning (recorded April–September 2001), was released by the Blood Fire Death label in 2002. Southern Lord Records re-released a remastered double-LP version in 2005. In the following years, Xasthur's releases were issued through a variety of labels including Bestial Onslaught Productions, Moribund Records, Profound Lore Records, Battle Kommand Records, Autopsy Kitchen Records, Hydra Head Records, Turanian Honour Productions, Avantgarde Music and Disharmonic Variations.

Xasthur released several split albums with other black metal acts such as Acid Enema, Angra Mainyu, Black Circle, Nachtmystium, Leviathan, Nortt and Striborg; contributed to tribute albums to Burzum, Ildjarn, Judas Iscariot, Katatonia and Manes; and appeared on various compilation albums. Additionally, Conner collaborated with numerous bands including the drone metal project Sunn O))), Mord (with Lugubre members), Celestia and Gravesideservice, and participated on the first album by black metal supergroup Twilight.

On March 26, 2010, Conner announced that he was wholesaling Xasthur's eighth studio album, Portal of Sorrow. He also stated that this would be the last album under the Xasthur moniker, as he was dissolving the Xasthur musical project.^[3] Conner cited a lack of motivation, among other aspects, for ending Xasthur; he also stated that there would not be a reunion of this band. Conner remarked that another, non-metal musical project was in the works,^[4] later revealed to be called Nocturnal Poisoning, named after his 2002 album. Nocturnal Poisoning released three albums between 2012 and 2014: Other Worlds of the Mind, A Misleading Reality and Doomgrass.

On September 30, 2010, Conner released the first and only music video to date under the Xasthur name, for the song "Walker of Dissonant Worlds" from the To Violate the Oblivious album.^[5]

Conner was featured in One Man Metal, a 2012 Noisey documentary,^[6] alongside Jef Whitehead of Leviathan and Russell Menzies of Striborg. Despite having been released in 2012, the interviews were conducted in 2009.

On March 5, 2015, Conner announced on the official Nocturnal Poisoning Facebook page that the band were reverting to the name Xasthur. In reclaiming the name, he said: "For five years, Nocturnal Poisoning was locked out and denied every opportunity or open door that Xasthur used to have, or would've had. I worked hard at building up both projects, starting both of them from nothing and nowhere, but I'm taking back what's mine. Xasthur doesn't belong to the greedy hipsters that milk the metal business; it belongs to me and it's mine to take back." He noted that a new Xasthur album would be available in 2016 on the Disharmonic Variations label, and that the current version of the band (including contributions from Nocturnal Poisoning associate members Christopher Hernandez and Robert Nesslin) would be a continuation of Nocturnal Poisoning's acoustic-driven music, saying, "There's no need to rehash old Xasthur songs, the acoustic ones are plenty dark, and sometimes they're not. If you've been listening, reading, thinking and getting it, we could call it Xasthur acoustic/unplugged with, whatever, a country, blues, 'folk', bluegrass, doomgrass or singer/songwriter style and technique in it".^[7][8]

On April 16, Xasthur's first-ever live concert appearance was announced, to take place on June 19, 2015 at the Thirst for Light: Cascadian Summer Solstice II festival at Red Hawk Avalon in Pe Ell, Washington.^[9]

On September 4, the title for the next Xasthur album was announced as Subject to Change;^[10] it was released May 6, 2016 by Disharmonic Variations.

Conner has noted other one-man black metal projects such as Burzum and Graveland^[11] as an inspiration for his singular approach: "The main way that Burzum inspired me (contrary to popular belief) was that he could do it all on his own-- why couldn't I?" Although similar in terms of low fidelity production and the wearing of corpse paint, musically and lyrically, the focus of the first edition of Xasthur was usually not on paganism, Satanism or anti-Christian blasphemy – as is common in the black metal genre – but rather on astral projection, darkness, despair, suicide, hate and death.

Conner has toured with Sunn O))) and has joined Nachtmystium onstage,^[12] but until recently, stated that he "will always keep Xasthur a band that will not play live".^[11] However, Xasthur's first live concert took place in June 2015.^[9]
