Keigo Oyamada (小山田 圭吾 Oyamada Keigo , born January 27, 1969 in Setagaya, Tokyo, Japan) is a Japanese recording artist and producer better known by his stage name Cornelius (CORNELIUS（コーネリアス） Kōneriasu ).
Oyamada's first claim to fame was as a member of the pop duo Flipper's Guitar, one of the key groups of the Tokyo Shibuya-kei scene. Following the disbandment of Flipper's Guitar in 1991, Oyamada donned the "Cornelius" moniker and embarked on a successful solo career.
American music journalists often describe Cornelius's musical style as being similar to Beck Hansen's, whom he acknowledges as an influence along with The Beach Boys, The Jesus and Mary Chain, Primal Scream and the Brazilian band Kassin + 2, among others.
The music of Cornelius could be described as experimental and exploratory, and often incorporates dissonant elements alongside more familiar harmonically "pleasing" sounds. This tension, plus his practice of bringing in sounds and samples from mass culture, pure electronic tones, and sounds from nature (such as on his Point album), lead him to being sometimes categorized as an "acquired taste."
In 2006 and 2007 respectively, the song "The Micro Disneycal World Tour" from the Fantasma album, was used for Nick Parks' "Creature Comforts" and Sky television's "See, Surf, Speak" advertisements in the UK. It had also been used several years earlier in an ironic NFL (US football) television commercial in the USA, which juxtaposed the song's relaxing qualities with video clips showing rapid, aggressive football playmaking.
In 2010 he contributed the song "Katayanagi Twins Battle Song" to the film Scott Pilgrim vs. The World
The discography of Cornelius consists of seven studio albums, one soundtrack, seven remix albums, three extended plays, twelve singles and seven video albums.
