Atheist, parts III and IV. For me

However, the music of Atheist is not so far from the traditions of metal. In addition to the fact that this band plays ordinary rock instruments, they draw on aspects of metal music created before it came to being. In the first place, these are harsh vocals. People usually associate metal with energy and power rather than melody, rhythm and technical skills, and this association rises mostly from growling and screaming vocals often used in metal. Overdriven guitar sound, the use of guitar as a rhythmic support, emphasis on fingerwork rather than liveliness typical for African American music - all of this is the legacy of "white", European heavy metal culture.

Combining the diversity of jazz and the power and technicality of metal, Atheist made up the new approach to making music. The style this band invented, jazz metal, might be interesting to a larger audience than the usual attenders of death metal shows. Jazz metal goes beyond the frames of cultural environment typical for heavy metal.
