context_page_description: A number of heavy metal genres have developed since the emergence of heavy metal during the late 1960s and early 1970s. At times heavy metal genres may overlap or are difficult to distinguish, but they can be identified by a number of traits. They may differ in terms of: instrumentation, tempo, song structure, vocal style, lyrics, guitar playing style, drumming style, and so on.
context_section_description: Avant-garde metal or avant-metal, also known as experimental metal, is a subgenre of heavy metal music loosely defined by use of experimentation and characterized by the use of innovative, avant-garde elements, large-scale experimentation, and the use of non-standard and unconventional sounds, instruments, song structures, playing styles, and vocal techniques. It evolved out of progressive rock, jazz fusion, and extreme metal, particularly death metal. Some local scenes include Los Angeles and the San Francisco Bay Area in the United States, Oslo in Norway, and Tokyo in Japan. Pioneers of experimental metal include Boris, Celtic Frost, Earth, Helmet, Maudlin of the Well, Neurosis, Sunn O))), and Voivod.
