6. Industrial Metal Without the industrial age, metal wouldn't exist, and without the digital age, industrial metal would flicker off. Industrial metal places every instrument that plugs in into metal -- synthesizers, samplers -- which is aligned with sharp repetitive guitar riffs and distorted vocals. Harsh, electronic noise sampling is used as an instrument and is meticulously integrated into the metal like an electrician wiring a house. Many industrial metal bands like to shock their listeners with a nine-volt battery on the tongue, attention-grabbing lyrics and intense light-flashing stage shows.
5. Stoner Metal Stoner metal is almost self explanatory. It's metal that was taken from furious fingers and twitchy feet and dumped into a swamp to musically trudge through waist high mud. Stoner metal almost sounds like your walkman or Discman is running out of battery power. Tempos and vocals are slowed down so much that it's surprising it doesn't completely stop. Metal, blues and psychedelic rock along with a gritty retro recording value burns smoothly for the ears, for a more internally irate lethargic listener.
4. Glam Metal The never-ending argument for the ages in the metal community is whether glam metal is even a subgenre of metal with its pop heavy derived sound caked with hairspray and makeup. This subgenre can be distinguished the fastest out of any subgenre due to its immense popularity in the '80s. Primarily formed on L.A.'s Sunset Strip, it became all-the-rage with the emergence of music videos. It's surprising that death metal fans haven't slaughtered all glam metal fans yet.
