'''Heavy metal''' is a genre of rock music, characterized by its loudness and aggressiveness.  

It emerged from bands like [[King Crimson]], [[Black Sabbath]] and [[Led Zeppelin]], amid the [[society|social]] upheavals of the late 1960s. [[Rock and roll|Rock music]] was by then being recorded and [[marketing|marketed]] as a counterculture which opposed the normal and functional culture that was dominant in society, a marketing [[strategy]] which mirrored the developmental process of [[adolescent]]s, the main audience for rock music, who first reject the world of their parents, then once independent re-assess their own values, and finally rejoin society on the terms of these recreated values.

The first style of rock which grew from this was the loud, distorted [[blues]] sound created by [[San Francisco]] based [[psychedelia]] band, '''Blue Cheer''', whose influence on electric blues bands could be seen from [[Cream (rock band)|Cream]] to [[Jimi Hendrix]] to '''ZZ Top'''. The second style was [[progressive rock]], which in 1968 was led by [[England|English]] band '''King Crimson''', combining jazz, classical, experimental, psychedelic and folk music. The precursor to this sound was [[The Beatles]], arguably the first band to leave the standard rock format, creating longer song structures, many of which were narrative or [[opera|neo-operatic]]. This was the main inspiration for later bands such as '''Camel''', [[Genesis (band)|Genesis]] and [[Yes (band)|Yes]].
