There are several artists named KRAKATAU: 1. avant-fusion band led by guitarist Raoul Björkenheim. 2. Indonesian jazz outfit. They play fusion at first, but then experimenting by merging indonesian ethnic style with western jazz. 3. Russian experimental metal band which was formed in Moscow in 2004, inspired by the experiments of Mike Patton, and other worthy guru, so the band has always been close to the spirit of musical freedom.
