The band formed after Steve Naghavi and Chris Ruiz met in 1989 at a Berlin club. Being fans of early EBM music, Naghavi and Ruiz decided to follow in the footsteps of new wave/synthpop band Depeche Mode by using two keyboards and a beatbox. Jason Ankeny of AllMusic called their 1990 single, "Metal Hammer", a "significant club hit". The duo became a trio with the addition of Alex Two, prior to the release of their debut album, Anguish in 1991. That same year, they were honored as the Best New Artist in Germany.
Going into the release of Anguish, they had already garnered a decent following through touring and appearances at various parties. With their debut release, they took home the Best New Artist award in Germany in 1991. Chris Ruiz left in 1992 (he would later return in 2001) while Steve Naghavi remained with the band. And One released three more albums with Machinery Records, Flop! (1992), Spot (1993) and I.S.T. (1994). The band left Machinery around 1996–1997 and signed to Virgin Schallplatten. And One would release four albums on this label between 1997 and 2003: Nordhausen (1997), 9.9.99 9 Uhr (1998), Virgin Superstar (2000) and Aggressor (2003).
The next And One album, Bodypop, was released on 1 September 2006 by Out of Line in Europe and on 7 November 2006 on Metropolis Records in the US. The single "Military Fashion Show" preceded the album. The band pulled out of their 2007 US tour with VNV Nation for unknown reasons.
In November 2007, And One announced the release of Bodypop 1½, an EP with covers of songs by Depeche Mode ("Never Let Me Down Again"), Front 242 ("Operating Tracks"), D.A.F. ("Der Mussolini"), Nitzer Ebb ("I Give to You") and The Cure ("Kyoto Song"). Three weeks later, the EP was cancelled and a full-length cover album announced. The album was finally released on 30 January 2009, but with a completely different track listing, featuring live cover versions of various synthpop hits such as New Order's "Blue Monday" and Pet Shop Boys' "It's a Sin".
The band's next album, Tanzomat, was released on March 4, 2011. A single, "Zerstörer" was released on January 21 prior to the album, but is not included on the album.
On June 4, 2011, Chris Ruiz and Gio van Oli announced they were leaving And One; they formed a new band called PAKT. Four days later, on June 8, 2011, Steve Naghavi announced the return of both Joke Jay and Rick Schah via the band's official Facebook page. The band's new album, S.T.O.P., was released on May 25, 2012. Two singles have been released to promote the record.
On August 8, 2014, And One released their 12th studio album Magnet. The album was released by itself, and as the Magnet Trilogie I Box in regular and limited editions on C.D. and vinyl.
