By the late 1960s, referred to as the "golden age" or "classic rock" period, a number of distinct rock music sub-genres had emerged, including hybrids like [http://en.wikipedia.org/wiki/Blues_rock blues rock], [http://en.wikipedia.org/wiki/Folk_rock folk rock], [http://en.wikipedia.org/wiki/Country_rock country rock], and [http://en.wikipedia.org/wiki/Jazz_fusion jazz-rock fusion], many of which contributed to the development of [http://en.wikipedia.org/wiki/Psychedelic_rock psychedelic rock], which was influenced by the countercultural [[psychedelic]] scene. New genres that emerged from this scene included [http://en.wikipedia.org/wiki/Progressive_rock progressive rock], which extended the artistic elements; [http://en.wikipedia.org/wiki/Glam_rock glam rock], which highlighted showmanship and visual style; and the diverse and enduring major sub-genre of [http://en.wikipedia.org/wiki/Heavy_metal_music heavy metal], which emphasized volume, [[power]], and [[speed]]. In the second half of the [http://en.wikipedia.org/wiki/1970s 1970s], [http://en.wikipedia.org/wiki/Punk_rock punk rock] both intensified and [[reacted]] against some of these trends to produce a raw, energetic form of music characterized by overt [[political]] and social critiques. Punk was an [[influence]] into the [http://en.wikipedia.org/wiki/1980s 1980s] on the subsequent development of other sub-genres, including [http://en.wikipedia.org/wiki/New_wave_music new wave], [http://en.wikipedia.org/wiki/Post-punk post-punk] and eventually the [http://en.wikipedia.org/wiki/Alternative_rock alternative rock] movement. From the [http://en.wikipedia.org/wiki/1990s 1990s] alternative rock began to dominate rock music and break through into the [[mainstream]] in the form of [http://en.wikipedia.org/wiki/Grunge grunge], Britpop, and indie rock. Further fusion sub-genres have since emerged, including pop punk, rap rock, and [http://en.wikipedia.org/wiki/Rap_metal rap metal], as well as conscious attempts to revisit rock's history, including the garage rock/post-punk and synthpop revivals at the beginning of the new millennium.

Rock music has also embodied and served as the vehicle for cultural and [[social movements]], leading to major sub-cultures including mods and rockers in the UK and the hippie [[counterculture]] that spread out from San Francisco in the US in the 1960s. Similarly, 1970s punk culture spawned the visually distinctive [http://en.wikipedia.org/wiki/Goth_subculture goth] and [http://en.wikipedia.org/wiki/Emo emo] subcultures. Inheriting the folk tradition of the [[protest]] song, rock music has been associated with political activism as well as changes in social [[attitudes]] to [[race]], [[sex]] and drug use, and is often seen as an [[expression]] of [[youth]] revolt against adult consumerism and [[conformity]].
