Motorpsycho were formed in the fall of 1989 by guitarist Hans Magnus "Snah" Ryan, bassist Bent Saether, and drummer Kjell Runar "Killer" Jenssen, who all knew one another from playing the regional club circuit with various bands. After cutting a demo in 1990 (which was released under the title Maiden Voyage) and releasing their debut LP, Lobotomizer, in 1991, Jenssen left the band and Håkon Gebhardt, a high-school friend of Ryan's, took over behind the drums.
After a handful of EPs and vinyl-only releases, the new Motorpsycho lineup added a fourth member, Helge Sten on keyboards and electronics, and they cut the grand-scale 1993 double album Demon Box, which earned enthusiastic reviews while expanding the group's following. The band stayed busy in the studio, releasing a pair of EPs in late 1993 and early 1994, leading up to Timothy's Monster, an expansive work spread out over two discs on CD and three LPs on vinyl. After the release of Timothy's Monster, Sten dropped out of Motorpsycho as a full-time bandmember, though he continued to work with the group in the studio and appeared at their live shows as his schedule permitted; guitarist Morten Fagervik and keyboardist Lars Lien came aboard in his place.
In 1995, the group released The Tussler, the original soundtrack album to a movie that existed only in Motorpsycho's imagination, and despite a busy touring schedule, they returned with another album, Blissard, in 1996. By the time Angels and Daemons at Play was released in 1997, Fagervik and Lien had dropped out of the group, and the core trio of Ryan, Saether, and Gebhardt soldiered on, releasing their next studio effort, Trust Us, in 1998, and the first in their series of Roadwork albums (collecting live recordings from the group's archives) in 1999.
In the 21st century, Motorpsycho kept up a hectic recording and performing schedule, releasing four studio albums, another Roadwork volume, and a collaborative EP with Jaga Jazzist Horns between 2000 and 2003; during this period, elements of jazz and electronic music also began playing a larger role in their music. In 2005, Gebhardt left Motorpsycho, and the 2007 album Black Hole/Blank Canvas found Ryan and Saether recording as a duo with guest percussionist Jacco van Rooij and vibraphonist Oyvind Brandtsegg. Released in 2008, Little Lucid Moments marked the recording debut of Motorpsycho's new full-time drummer, Kenneth Kapstad, and in 2009 the band celebrated its 20th anniversary with a vinyl-only album, Child of the Future, recorded with engineer Steve Albini. Another studio set, Heavy Metal Fruit, was released in 2010 and the fourth Roadwork collection followed in 2011. In 2012, Motorpsycho collaborated with keyboardist/composer/arranger Ståle Storløkken (Supersilent, Elephant9, Humcrush, Terje Rypdal) and the Trondheim Jazz Orchestra. They released a re-imagined studio version of the 2011 concert work The Death Defying Unicorn, which was commissioned by the Molde International Jazz Festival for their 50th anniversary. They returned with the genre-defying Still Life with Eggplant in 2013, and followed it with the sprawling Behind the Sun in March of 2014. Later that spring the band announced The Motorpnakotic Fragments, an extremely limited-edition (1,200) album created from four 7" vinyl singles; also included was a disc of the entire album. It was shipped throughout the fall of 2014. Motorpsycho kicked off 2015 with a deluxe five-disc reissue of their 1993 album, Demon Box. Originally recorded as a double, it was trimmed and released as a single album. The set restored the entire recording in proper sequence, was fully remastered, and contained bonus EPs, rarities, and a concert video disc. It was followed by a live acoustic vinyl offering entitled En Konsert for Folk Flest. Also that year, Rockheim, the Norwegian national museum of rock, displayed a 25-year retrospective exhibition of the band called Supersonic Scientists. For the first time in their career, Motorpsycho assembled a retrospective collection; entitled Supersonic Scientists: A Young Person's Guide to Motorpsycho, it featured one track each from their "regular" studio album catalog outside of soundtracks, live recordings, collaborations, or special projects. It was followed in February by a brand-new single, a cover of H.P. Lovecraft's version of Terry Callier's "Spin Spin Spin." The full-length Here Be Monsters was released a month later. The album's origins lay in a commission for the centennial jubilee of the Norwegian Technical Museum in November 2014. The music was written for the expanded version of Motorpsycho that featured Storløkken, though he did not participate in the recording sessions due to time constraints. Following the touring for Here Be Monsters, drummer Kapstad left the band, leaving Sæther and Ryan to write and rehearse their live score for the Carl Frode Tiller play Begynnnelser. In 2017, a double-live album and DVD of Begynnelser was released. It was also announced that drummer Tomas Järmyr had joined Motorpsycho as a full-time member. He made his studio debut on the 2017 double LP The Tower. the band followed with The Crucible, a three track album that in visual design and music, began where The Tower ended, but could not strictly speaking be referred to as a "sequel." Broader lyrically and more sharply focused and idiosyncratic musically, it was recorded at Monnow Valley Studios in Wales during August 2018, with co-producers Andrew Scheps and Deathprod and issued in March of the following year.
In 2020, Motorpsycho completed its informally titled "Gullvåg Trilogy" -- initiated by The Tower and continued on The Crucible --with The All Is One. Recorded in France and Norway between September and November of the previous year, the double-length album was planned for a spring release but postponed until summer. Undaunted, the band used the extra time, returned to the studio, and carefully detailed the recording. The All Is One was issued by Rune Grammofon in August. ~ Mark Deming, Rovi
