Musically interesting and unusual, but the godawful lyrics really ruin it for me. That said, "Köpfe aus Stein" is the best track - it's got a certain drive and the lyrics are interesting (the video is also worth checking out). Last track somewhere between a really nice riff in the beginning, a beautiful ending after the clean vocals stop - and the tedious middle part with terrible rhymes. Probably more enjoyable if you don't speak German.
Favorite track: Köpfe aus Stein.
