In 2004 they switched label to the now defunct Supersonic Records (a subsidiary of Sony BMG) and their work moved away from the band's electronic roots to the heavier Neue Deutsche Härte (New German hardness) genre.

They released their first album, Lieder die wie Wunden bluten, in 1997 on MOS Records in Liechtenstein, which became popular in the underground German dark culture.

In 2003, L'Âme Immortelle released Als die Liebe starb, as well as Seelensturm, a collection of re-issued and re-mixed early material.

on the initially non-album (it was later inlided on a re-edition of the album Wahrheit oder Pflicht) single "Brennende Liebe" (released as Oomph!

Following that, L'Âme Immortelle released a new album, Gezeiten, which includes some of their most popular songs like "5 Jahre", "Stumme Schreie" and "Fallen Angel".

A significant change in L'Âme Immortelle's style is evident now that the band is on a major label, notably the electronic instrumentation of earlier work was less prominent in Gezeiten.
