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. ~ Mark Deming, Rovi
