Their original style (featured on their releases up to and including Allegro Barbaro) consists of death/thrash metal blended with melodic compositions establishing a more epic mood than usual in traditional death metal. In later albums, the death metal influence has declined, resulting in less chaotic composition (often centered around a verse and chorus with a bridge and solo), more constant tempo, longer songs and clean vocals (although not exclusively), resulting in a more polished and accessible sound. They use lyrics in both English and German with a shift from mainly English songs to more German ones on recent albums.
The release of "Have a Nice Trip" marked somewhat of a turning point for the band. Although they retained the essence of Heavy Metal, they began experimenting with many other styles of music such as Ambient, Jazz, and even Reggae.
