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.
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.
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.
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.
Australian heavy metal
Australian heavy metal music has its roots in both the Australian hard rock and pub rock tradition of the 1970s and the American and British heavy metal scenes. Since the mid-1980s, Australian heavy metal has been particularly influenced by foreign bands, particularly Swedish death metal, American thrash metal and black metal from Norway. Within Australia heavy metal has always remained part of the underground but since the mid-1990s many Australian metal acts have found widespread acceptance in overseas markets, particularly in Europe. AC/DC is often cited as being Australia's foremost hard rock band.
Heavy metal subculture
Fans of heavy metal music have created their own subculture which encompasses more than just appreciation of the style of music. Fans affirm their membership in the subculture or scene by attending metal concerts–an activity seen as central to the subculture, buying albums, in some cases growing their hair long, wearing leather jackets and t-shirts with band names and logos and most recently, by contributing to metal websites. Metal fans may also write or take photos for metal zines. Some critics and musicians have suggested that the subculture is largely intolerant to other musical genres. The metal scene, like the rock scene in general, is associated with alcohol, tobacco and drug use as well as riding motorcycles and having a lot of tattoos.
Heavy metal lyrics
Heavy metal lyrics are the words used in songs by heavy metal artists. Given that there are many genres of heavy metal, it is difficult to make generalizations about the lyrics and lyrical themes. In 1989, two metal scholars wrote that heavy metal lyrics concentrate "on dark and depressing subject matter to an extent hitherto unprecedented" in any form of popular music. Jeffrey Arnett states that metal songs are "overwhelmingly dominated" by "ugly and unhappy" themes which express "no hope" for the future. Deena Weinstein has proposed one way to analyze metal song themes is loosely grouping them into two categories: the Dionysian theme (a reference to the Roman God of wine), which celebrates "sex, drugs and rock and roll", partying, and enjoyment of life and the Chaotic theme, which involves dark subjects such as Hell, injustice, mayhem, carnage and death.

Rock music
Rock music is a broad genre of popular music that originated as "rock and roll" in the United States in the early 1950s, and developed into a range of different styles in the 1960s and later, particularly in the United Kingdom and in the United States. It has its roots in 1940s and 1950s rock and roll, a style which drew heavily on the African-American genres of blues and rhythm and blues, and from country music. Rock music also drew strongly on a number of other genres such as electric blues and folk, and incorporated influences from jazz, classical and other musical styles. Musically, rock has centered on the electric guitar, usually as part of a rock group with electric bass and drums and one or more singers.
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.

American rock
American rock is rock music from the United States. It has its roots in 1940s and 1950s rock and roll, rhythm and blues, and country music, and also drew on folk music, jazz, blues, and classical music. American rock music was further influenced by the British Invasion of the American pop charts from 1964 and resulted in the development of garage rock. From the late 1960s and early 1970s, American rock music was highly influential in the development of a number of fusions, including blending with folk music to create folk rock, with blues to create blues rock, with country music to create country rock, roots rock and southern rock and with jazz to create jazz rock, all of which contributed to psychedelic rock.
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.
Music history of the United States in the 1960s
Popular music of the United States in the 1960's became innately tied up into causes, opposing certain ideas, influenced by the sexual revolution, feminism, Black Power and environmentalism. This trend took place in a tumultuous period of massive public unrest in the United States which consisted of the Cold War, Vietnam War, and Civil Rights Movement. Central to this trend was a folk roots revival that inspired a wave of similar trends across Europe and the rest of the world. This stemmed from a revival of hillbilly music early in the decade, and drew on Appalachian folk-pop pioneers The Weavers.
1960s in music
This article includes an overview of the events and trends in popular music in the 1960s. In North America and Europe the decade was particularly revolutionary in terms of popular music, as it saw the evolution of rock. At the beginning of the 1960s, pop and rock and roll trends of the 1950s continued; nevertheless, the rock and roll of the decade before started to merge into a more international, eclectic variant known as rock. In the early-1960s, rock and roll in its purest form was gradually overtaken by pop rock, beat, psychedelic rock, blues rock, and folk rock, which had grown in popularity.
