在所有摇滚乐的无数形式中，重金属是体积，机械大学和戏剧性最极端的。重金属的核心声音有许多风格变化，但它们都通过依赖响亮，扭曲的吉他（通常玩重复的riffs）和简单，砰砰的节奏而系在一起。重金属在其存在之中几乎存在争议 - 批评者传统上将音乐解雇为凭借过度的青少年戏剧，保守团体经常抗议他们认为是邪恶的抒情内容的邪恶。尽管如此，仍然是因为 - 由于 - 那些困难，重金属已成为有史以来最持续流行的摇滚音乐形式之一，能够适应时期，但保持其核心吸引力。对于所有国家的选择，因为美国的叛乱音乐配乐，重金属主要是英国创造。在60年代的英国蓝调运动中播种了重金属的第一个种子，特别是在乐队中发现它难以适应美国蓝调的自然摇摆。节奏变得更加平方，而放大的电气仪器变得更加重要，特别是与像扭结的艺术家的创新，世卫组织，吉米亨德里克斯，奶油和杰夫贝克集团。然而，可以说是第一个真正的金属带是LED Zeppelin。最初，ZEP播放了蓝调曲调比任何人都更重，胜过，很快就创造了一种史诗般的纹理品牌的重型岩石，从许多音乐来源中画出。不那么微妙，但也许更有影响力的是黑人安息日，其朦胧，吉他吉他牧师创造了一个破坏毒品，死亡和神秘的失败者幻想世界。 Following the blueprint laid down by Zep and Sabbath, several American bands modified heavy metal into more accessible forms during the '70s: the catchy tunes and outrageous stage shows of Alice Cooper and Kiss; the sleazy boogie of Aerosmith; and the flashy guitar leads and wild party rock of Van Halen (not to mention the distinctively minimalist grooves of Australia's AC/DC). In the late '70s, a cache of British bands dubbed the New Wave of British Heavy Metal (including Judas Priest, Iron Maiden, and Motorhead) started playing metal faster, leaner, and with more menace than ever before. They helped influence a new American metal scene known as thrash in the '80s, which took shape as a reaction to metal's new mainstream pop breakthrough, which came courtesy of Def Leppard's Pyromania. Metal enjoyed its greatest presence on the charts during the '80s, thanks to a raft of glammed-up pop-metal bands, but thrash bands played complex riffs at breakneck speed, sometimes dispensing with vocal melody altogether. Thrashers like Metallica and Megadeth built rabid cult followings that pushed them into the mainstream around the same time that grunge wiped pop-metal off the charts. Mainstream metal in the '90s centered around a new hybrid called alternative metal, which (in its most commercially potent form) combined grinding thrash and grunge influences with hip-hop and industrial flourishes, though it broke with metal's past in downplaying the importance of memorable riffs. Meanwhile, the underground grew harsher and bleaker, producing two similar, thrash-derived styles known as death metal and black metal, which produced some of the most abrasive, intense, hyperspeed music and graphic shock tactics the metal world had yet witnessed.
