Mental Overdrive is the primary solo moniker of Per Martinsen (born 31 July 1966), one of Norway's most prolific and influential techno musicians.
 His tracks have ranged from hardcore rave techno to vibrant space-disco, and he's always maintained a healthy balance of humor and braininess.
 Active since 1990, he began his career releasing several 12" EPs of aggressive, rave-ready hardcore techno on revered Belgian label R&S, including 12000 AD (1990), The Second Coming (1991), Move!
 (as Confusion Club, 1991), and The Love EP (1992).
 In 1994, Martinsen began releasing atmospheric techno singles as part of Illumination, his duo with Nicholas Sillitoe.
 The next year, Mental Overdrive released the single "Disto Disco," which featured a B-side ("Faith") co-written by R&S artist Outlander, best known for the 1991 classic "Vamp."
 The A-side appeared on Mental Overdrive's full-length debut Plugged, released on Martinsen's own Love OD Communications.
 The album showed a notable progression in his music, maintaining its rough, distorted hardcore techno sound while adding more cerebral elements, placing it closer to Warp's Artificial Intelligence series.
 Martinsen displayed his sense of humor with 1996's Unplugged, a limited conceptual release containing silent "versions" of the tracks on Plugged.
 083 In 1997, Mental Overdrive signed to Virgin and released About Jazz, a significantly more house/disco-influenced EP than his previous work.
 This was followed by full-length Ad Absurdum, which continued in a more light-hearted and funky direction than his previous releases.
 He took a few years off from releasing Mental Overdrive recordings, instead devoting time to Frost (his more pop-focused electronic duo with his wife Aggie Peterson) and Illumination, which released two albums on RCA.
 Following the 2003 release of Mental Overdrive's Me EP on Love OD, he signed to Norwegian label Smalltown Supersound and released full-length 083, which featured the single "Diskodans."
 In 2005, the label compiled his early R&S material on CD as The Phuture That Never Happened.
 Two years later, Mental Overdrive's single "Spooks" appeared on Prins Thomas' Full Pupp label.
 The song appeared on his next Smalltown full-length, You Are Being Manipulated, which was released in 2008.
 The album was perfectly at home with the label's other left-field dance artists like Bjørn Torske and Kim Hiorthøy, while maintaining the unique Mental Overdrive sound.
 Martinsen continued releasing Mental Overdrive singles on Full Pupp and Love OD, and contributed to Rune Lindbæk's Meanderthals project.
 In 2012, he released Man with a Movie Camera, an EP featuring music he'd composed for a 1996 screening of the Russian silent film of the same name, which also featured pieces by Biosphere which would later appear on the 2001 remaster of his classic album Substrata.
 Mental Overdrive returned to his Love OD label for 2013 full-length Cycls, as well as 2014's Everything Is Connected, which compiled a few previously released EPs.
 In 2016, Full Pupp sublabel Rett I Fletta released a new version of Plugged consisting of alternate takes sourced from the original DAT tapes.

Infinity Ink is a London-based vocal/music production/DJ duo made up of Italian Luca C and Briton Ali Love.
 They have released music through Hot Creations, Crosstown Rebels and, most recently, Different Recordings.
 Originally they formed the duo The Benedictions, playing 1960s and 1970s folk rock-inspired music on acoustic guitar.
 The name of the duo Infinity Ink came when the duo were playing in Moldova on their tour.
 They noticed a nearby factory that was called 'Infinity Inc'.
 So they adopted the name changing the "c" to a "k", giving it a completely new twist.

Rave music may either refer to the late 1980s/early 1990s genres of house, breakbeat, acid house, techno and hardcore techno, which were the first genres of music to be played at rave parties, or to any other genre of electronic dance music (EDM) that may be played at a rave.
 The genre "rave", also known as hardcore by early ravers, first appeared amongst the UK "acid" movement during the late 1980s at warehouse parties and other underground venues, as well as on UK pirate radio stations.
 The genre would develop into oldschool hardcore, which lead onto newer forms of rave music such as drum and bass and 2-step, as well as other hardcore techno genres, such as gabber, hardstyle and happy hardcore.
 Rave music is usually presented in a DJ mix set, although live performances are not uncommon.
