The origin of the band's name is unclear.
In one interview, Berkman said the name 'Anamanaguchi' came about from a member in one of his former bands pronouncing gibberish in the style of Jabba the Hutt. (left to right) James DeVito, Peter Berkman and Ary Warnaar in Brooklyn, New York, in 2009 People began calling them the 'Armani-Prada-Gucci boys,' which eventually was elided into 'Anamanaguchi.' On several other occasions, the band has explained that their name came about after the members worked as interns at Armani (Berkman and DeVito), Prada (Warnaar), and Gucci (Silas) while studying fashion at Parsons School of Design (though three of the four majored in Music Technology at New York University). The band formed in Chappaqua, NY where Peter Berkman & James DeVito were classmates. The band first performed in January 2006 at Cake Shop and through events such as Pulsewave NYC they formed a relationship with the netlabel 8bitpeoples and subsequently released their debut the EP Power Supply in August 2006.
The track 'Helix Nebula' was featured as the theme song of the former GamesRadar podcast TalkRadar.
