Although the band has had, and still has, many members, only one person actually acted as vocalist at a time, while the other members didn’t do backing vocals and concentrated solely on their instruments. In the end, what actually caused the variety in their songs was the triple change of the singer instead.

1993–2003 Alexander Wesselsky
2003–2005 Mathias Elsholz
2007–now Alexander Wohnhaas

Funfact: Alexander Wesselsky is also the lead singer of the band Eisbrecher.
