Heavy metal music
Heavy metal (or simply metal) is a genre of rock music that developed in the late 1960s and early 1970s, largely in the United Kingdom. With roots in blues rock and psychedelic/acid rock, the bands that created heavy metal developed a thick, massive sound, characterized by highly amplified distortion, extended guitar solos, emphatic beats, and overall loudness. Heavy metal lyrics and performance styles are sometimes associated with aggression and machismo. In 1968, three of the genre's most famous acts, Led Zeppelin, Black Sabbath and Deep Purple were founded. Though they came to attract wide audiences, they were often derided by critics.
Acid rock
Acid rock is a loosely defined type of rock music that evolved out of the mid-1960s garage punk movement and helped launch the psychedelic subculture. The style is generally defined by heavy, distorted guitars, lyrics with drug references, and long improvised jams. Distinguishing acid rock from other genres can be tenuous, as much of the style overlaps with 1960s punk, proto-metal, and heavy, blues-based hard rock. The term, which derives its name from lysergic acid diethylamide (LSD), is sometimes deployed as a synonym of "psychedelic rock", but it may also refer to a more musically intense subgenre or sibling to the psychedelic rock style.
Heavy metal genres
A number of heavy metal genres have developed since the emergence of heavy metal (often shortened to "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. Alternative metal is a style of heavy metal and alternative rock which emerged in the mid-1980s, and gained popularity in the early 1990s. Alternative metal usually combines heavy metal with influences from genres like alternative rock, and in some cases other genres not normally associated with metal as well.
Psychedelic rock
Psychedelic rock is a diverse style of rock music inspired, influenced, or representative of psychedelic culture, which is centred around perception-altering hallucinogenic drugs. Psychedelic rock is intended to replicate and enhance the mind-altering experiences of psychedelic drugs, most notably LSD. Many psychedelic groups differ in style, and the label is often used indiscriminately. Originating in the mid-1960s among British and American musicians, the sounds of psychedelic rock invokes three core effects of LSD: depersonalization, dechronicization, and dynamization; all of which detach the user from reality.
Nu metal
Nu metal (also known as nü-metal and ) is a form of that combines elements of with elements of other music genres such as hip hop, alternative rock, funk and grunge. bands have drawn elements and influences from a variety of musical styles, including multiple genres of heavy metal. rarely features guitar solos; the genre is heavily syncopated and based on guitar riffs. Many nu metal guitarists use that are down-tuned to play a heavier sound. DJs are occasionally featured in nu metal to provide instrumentation such as sampling, turntable scratching and electronic backgrounds. Vocal styles in include singing, rapping, screaming and growling.
Christian metal
Christian metal, also known as white metal, Jesus metal or heavenly metal, is a form of heavy metal music usually defined by its message using song lyrics as well as the dedication of the band members to Christianity. Christian metal is typically performed by professed Christians principally for Christians who listen to heavy metal music and often produced and distributed through various Christian networks. Christian metal bands exist in most of the subgenres of heavy metal music, and the only common link among most Christian metal bands are the lyrics. The Christian themes are often melded with the subjects of the genre the band is rooted in, regularly providing a Christian take on the subject matter.
Acid mine drainage
Acid mine drainage, acid and metalliferous drainage (AMD), or acid rock drainage (ARD) is the outflow of acidic water from metal mines or coal mines. Acid rock drainage occurs naturally within some environments as part of the rock weathering process but is exacerbated by large-scale earth disturbances characteristic of mining and other large construction activities, usually within rocks containing an abundance of sulfide minerals. Areas where the earth has been disturbed (e.g. construction sites, subdivisions, and transportation corridors) may create acid rock drainage. In many localities, the liquid that drains from coal stocks, coal handling facilities, coal washeries, and coal waste tips can be highly acidic, and in such cases it is treated as acid rock drainage.
