[1][2][3] Kajanus moved with his mother and sister to Paris at the age of twelve where he studied music and classical guitar, as well as attending the Cité Universitaire’s flying school.
[1] Kajanus was a member of UK-based folk rock band Eclection, who released a self-titled album in 1968[4] and wrote Cliff Richard's single "Flying Machine" (1971).
Deciding to form a group, tentatively named KP Packet, Kajanus and Pickett enlisted drummer and percussionist Grant Serpell (Affinity), and keyboard player and guitarist Henry Marsh (Gringo).
[5][6] Kajanus had developed a musical theater concept, Red Light Review, based on his memories of being a young man in places like Pigalle in Paris's red-light district.
The classical-oriented title track of DATA’s first album, Opera Electronica, was the theme music to the short film, Towers of Babel (1981).
Noir’s single "Walking" was used extensively in the 1997 Channel 4 television series Feast, an avant-garde culinary program directed by TV food maestro David Pritchard.
[5] Kajanus composed the soundtracks for two documentaries directed by German filmmaker Monika Treut: Didn't Do It for Love (1997) and the award-winning Gendernauts (1999).
