Although Brötzmann's compositions have sonic roots in hard rock, noise, prog rock, industrial, free-jazz and metal, his raw sound seems to exist outside of genres and conventions - combining elements of avant-garde composition, improvisation and tribal rhythms into an explosive sonic storm. A treat for fans of dense guitar sonic walls. In addition to the reborn Massaker, Caspar (son of legendary free-jazz saxophonist Peter Brötzmann and left-handed guitarist like Jimi Hendrix) has collaborated with Massimo Pupillo (ZU), Paige Hamilton (Helmet) and FM Einheit (Einstürzende Neubauten).
