Atticus Ross is the son of Ian Ross, a founder of Radio Caroline, and Roxana Lampson, daughter of British diplomat Miles Lampson, 1st Baron Killearn and Jacqueline Castellani. His great-grandfather was the noted pathologist and bacteriologist Aldo Castellani, KCMG (Hon.). Liberty Ross, the model, is one of his five siblings. He was educated at Eton College, in the same house as Earl Spencer. David Cameron was also a contemporary.
Atticus Ross first came to notice in the mid-1990s as a programmer for Tim Simenon's Bomb the Bass during the period of the albums Unknown Territory and Clear. He worked on a number of production and remix projects with Simenon as well as forming a collaborative relationship with former Bad Seed Barry Adamson. He programmed The Negro Inside Me and Oedipus Schmoedipus, and produced As Above So Below before forming his own band 12 Rounds with Claudia Sarne and Adam Holden. They released two albums, Jitterjuice (Polydor Records) and My Big Hero (Nothing Records). A third full-length album was produced by Trent Reznor for Nothing Records, but ultimately never finished. Three songs from that album have since been released at http://www.12rounds.net as of August 2011.
