The band's original line-up included Axel "Lexa" Schäfer on bass (until 1995 and again since 2007) and Ulli Lange on drums (until 1992).

In 1995, Heise's suicide caused the band to call a hiatus, which lasted until 2004.

She can also be heard on the alternative mix from "Alter Mann" which appeared on the single for "Das Modell" and in the song "Nebel", from 2001 album Mutter.

In 2005's, Rosenrot she sang on "Stirb nicht vor mir" in the German version of the song, which did not make the final cut, but she can be heard in the backing vocals of the English version, where the female lead was provided by Sharleen Spiteri.

However, Rammstein keyboardist Flake Lorenz has claimed he preferred the German version with Bobo's vocals.
