Alternative metal

Alternative metal (also known as alt-metal) is a rock music fusion genre that infuses heavy metal with influences from alternative rock and other genres not normally associated with metal. Alternative metal bands are often characterized by heavily downtuned, mid-paced guitar riffs, a mixture of accessible melodic vocals and harsh vocals and sometimes unconventional sounds within other heavy metal styles. The term has been in use since the 1980s, although it came into prominence in the 1990s.

Other genres considered part of the alternative metal movement included rap metal and funk metal, both of which influenced another prominent subgenre, nu metal. Nu metal expands the alternative metal sound, combining its vocal stylings and downtuned riffs with elements of other genres, such as hip hop, funk, thrash metal, hardcore punk and industrial metal.
