Early years (1989–2002)

Oomph! incorporated many styles of music such as metal, industrial, alternative rock, electronica and gothic to create their sound. Their style changed between their self-titled debut, Oomph! (1992), and its successor Sperm (1994). Though they started with very much a dance-laden industrial sound, they quickly moved to a much more heavily guitar-driven metal sound, while still acknowledging their electronic roots. This guitar-driven and electronic accompanied sound inspired numerous musicians, most famously Rammstein, Megaherz, and Eisbrecher, to follow their lead.

Oomph! was signed on Virgin Schallplatten between 1998 and 2001, where they released three albums; the first, Unrein, was released in 1998, which became their debut album on the German Media Control Charts, peaking at No. 37, and the Austrian top 40 at No. 38. A single called "Gekreuzigt" was released in 1998 to promote Unrein and became the band's debut single on the German charts, peaking at No. 81.

The second Virgin album, Plastik, was released in 1999 and peaked in Germany at No. 23. The third, Ego, was released in 2001, peaking at No. 21 on the Media Control Charts. This fulfilled their contract with Virgin; the band did not continue with the record company, feeling that it never fully explored their potential. With the benefits of major-label status, Oomph! gained a larger following and toured with labelmates Skunk Anansie in 1999, later opening for Finnish rock band HIM in fall 2001.

In 2002, Oomph! played at the Ozzfest in Germany, alongside Black Label Society, Tool and Ozzy Osbourne on 20 May. The band appeared at the With Full Force Festival on 5 July 2002. On 19 December 2002, Oomph! opened for Apoptygma Berzerk.

Wahrheit oder Pflicht and GlaubeLiebeTod (2004–2007)

In 2004, Oomph! released their first single, "Augen auf!" ("Open your eyes!"), from their eighth album Wahrheit oder Pflicht on a new label, this time on Supersonic Records, part of the Sony BMG group of music companies. It marks their first number one hit in Germany, eventually bringing forth their major commercial breakthrough. The album hit No. 2 on the Media Control Charts.

In June 2004, Oomph! played at two major European music festivals: the Dynamo Open Air Festival on 5 June in the Netherlands, and on 25 June at the Graspop Metal Meeting in Belgium.

The band's ninth album, GlaubeLiebeTod ("FaithLoveDeath"), was released in March 2006, including the controversial single "Gott ist ein Popstar" ("God is a popstar"), its follow-up "Das letzte Streichholz", "Die Schlinge", and "Träumst du?".

In August 2006, Virgin released the compilation album 1998–2001: Best of Virgin Years. It contains tracks from Oomph!'s three Virgin albums as well as a few unreleased tracks. The band distanced itself from this best-of release and asked that fans not buy it, as the band's current label GUN had scheduled a best-of compilation as well.

On 15 June 2006, Oomph! played at the Nova Rock Festival in Austria.

On 1 December 2006, Oomph!'s official best-of album, Delikatessen (Delicacies) was released under the GUN label. The songs on it were hand-picked by the band itself. It contains tracks from all nine Oomph! albums, B-sides, remixes, and new tracks like "The Power of Love" and "Gekreuzigt 2006". By 17 November 2006, Oomph! released those two songs in a form of double-single to promote the new compilation release.

On 9 February 2007, the band released their final GlaubeLiebeTod single "Träumst du?", featuring the female vocalist from Die Happy, Marta Jandová. The single peaked at No. 9 on the Media Control Charts. Oomph! performed the song live the same day at the 2007 edition of Bundesvision Song Contest, representing Lower Saxony in the competition, coming in first place.

On 6 July 2007, Oomph! opened for Metallica in Vienna, Austria.
