|Labels||AFM, Breaker, GUN, RCA|
|Associated acts||Accept, Gotthard, Bullet, Edge of Forever|
|Past members||Peter Szigeti|
Following Udo Dirkschneider's departure from Accept in 1987, he formed his own band called U.D.O. He recruited guitarists Mathias Dieth and Peter Szigeti, bassist Frank Rittel and drummer Thomas Franke. They released their debut album titled Animal House on 3 November 1987, which was entirely written by Accept. They would tour with the likes of Guns N' Roses, Lita Ford and Zodiac Mindwarp. Rubach, Rittel and Franke departed the band, and guitarist Andy Susemihl, bassist Thomas Smuzyszki and drummer Stefan Schwarzmann joined. In 1988, U.D.O. recorded the follow-up album Mean Machine, which was released on 10 January 1989.
Susemihl left the band, with U.D.O. now as four-piece. The band shifted to a lighter approach with the third album Faceless World, which was released on 25 February 1990, achieving great success; this being their best selling album so far. It was produced by ex-Accept drummer Stefan Kaufmann. The fourth album, Timebomb, was released on 3 April 1991, being a more heavier album than their previous releases. In 1992, Dirkschneider put U.D.O. on hiatus to reunite with Accept.
In 1996, Dirkschneider returned to U.D.O. with a brand new line-up; Stefan Kaufmann, now undertaking guitar duties, with guitarist Jürgen Graf and bassist Fitty Wienhold from Bullet hired as new members, and Stefan Schwarzmann returning to the band. They took part in the 1997 compilation album A Tribute to Judas Priest: Legends of Metal, in which they recorded the song "Metal Gods".
On 24 March 1997, U.D.O. released the fifth album Solid. It was featured on the Rock Hard magazine reader charts for more than a year after its release. The album was followed up with No Limits on 20 April 1998, featuring a similar songwriting approach to Solid. The album features a cover of the Austrian pop band Supermax's hit single "Love Machine". After the conclusion of the tour, Stefan Schwarzmann quit the band. New drummmer Lorenzo Milani replaced him.
The seventh album Holy was released on 18 October 1999, receiving critical acclaim. It was a return to the guitar-driven sound similar to the Balls to the Wall-era Accept. A world tour followed with dates in the United States and several other major countries. The band "Vanize", fronted by Udo Dirkschneider's brother Peter, supported U.D.O. during the tour. Line-up changes occurred during the second part of the tour with Gotthard guitarist Igor Gianola replacing Jürgen Graf. The tour spawned the first live album, Live from Russia, a two-disc affair, featuring many of the classic Accept tunes (with the exception of "Balls to the Wall") that have since become staples of U.D.O.'s set.
In 2001, the band recorded their eighth album Man and Machine, which was released on 24 July 2002. It received a somewhat lukewarm response. Despite standout songs like the title track and "Private Eye", the album was ultimately less successful than Holy. It is notable for the song "Dancing with an Angel", featuring a duet performance between Dirkschneider and Warlock vocalist Doro Pesch.
From August to December 2003, the band recorded their ninth studio album Thunderball, which was released on 29 March 2004. The follow-up album, Mission No. X, was originally due for release on 4 October 2005, but was pushed ahead by one week and was released on 30 September 2005. It is the first album to feature Edge of Forever drummer Francesco Jovino.
On 18 May 2007, the eleventh album Mastercutor was released. In August 2007, bassist Fitty Weinhold was unable to perform with the band due to "private reasons". He would be temporarily replaced with former Majesty bassist Marcus Bielenberg for touring purposes.
U.D.O.'s twelfth studio album, Dominator, was released on 21 August 2009. The next studio album, Rev-Raptor, was originally due for release on 14 January 2011, but was delayed until 18 March 2011 due to the recurrence of Stefan Kaufmann's back problems. It received another delay, and was finally released on 20 May 2011.
In September 2012, Kaufmann announced his departure for health reasons. He would continue to work in the surroundings of the band and produce for other bands in his own personal studio. On 15 January 2013, Russian guitarist Andrey Smirnov was recruited as the new member. On 24 January 2013, Igor Gianola left the band "due to conflicts between band appointments and his private life and business." Following his departure, former Amberian Dawn guitarist Kasperi Heikkinen joined the band. The fourteenth album, Steelhammer, was released on 20 May 2013.
In December 2014, drummer Francesco Jovino left the band for personal reasons, joining Primal Fear in 2015. He was replaced by Udo Dirkschneider's son, Sven in February 2015. U.D.O. released the fifteenth studio album Decadent on 23 January 2015.
In February 2017, Kasperi Heikkinen announced his departure citing personal reasons. According to the band, no bad blood or drama were involved between the two. In March 2017, guitarist Bill Hudson was announced as the new member. On 24 April 2018, Hudson parted ways with the band "due to a difference in their individual visions for the future", according to Dirkschneider, and added that there was no "negative feelings on either side."
In June 2018, Stefan Kaufmann temporarily rejoined the band only for the summer festival appearances until a new guitarist would be announced. The sixteenth album Steelfactory was released on 31 August 2018, with the first single "Rising High" being made available for streaming. On 19 September 2018, Fitty Wienhold announced his departure from U.D.O. He stated in a video message saying that he would remain with the band if needed, "as a songwriter, as a friend, as an advisor...whatever." The band soon recruited guitarist Dee Dammers and bassist Tilen Hudrap as their new members.
On 19 January 2019, the members of U.D.O. posted a message on Facebook saying that Dirkschneider was experiencing pain in his left knee since earlier in the month and would be "a bit handicapped on stage" during the band's upcoming tour. Dirkschneider would ignore orders from doctors and would continue performing despite his injury without causing disappointment to the fans.
In 2015, Udo Dirkschneider announced his plans to embark on a special tour in 2016 which he said was his "farewell to Accept", stating that he would no longer perform Accept songs again. U.D.O. would perform under the name Dirkschneider for the occasion, naming the tour "Back to the Roots". In early 2017, the band performed in North America. A 2-CD live album titled Live - Back to the Roots was released on 28 October 2016. An updated version titled Live - Back to the Roots - Accepted! was released on 4 August 2017, featuring a DVD of their performance from Brno.
In March 2017, Dirkschneider confirmed that he would continue to perform Accept songs for at least another year. After a positive reception during their North American tour in early 2017, Dirkschneider returned for a second run of shows for early 2018.
During a November 2017 interview with Czech magazine Spark, Dirkschneider said that his side project would no longer continue in 2018 as he did not want to cause confusion between U.D.O. and Dirkschneider.
