Classic rock evolved from swing music and jazz in the late 1960s, led by artists like The Beatles, The Rolling Stones, and Jimi Hendrix. Generally, classic rock includes rock songs from the 1960s-1980s. Some key characteristics of classic rock include older rock songs that are still popular on the radio today and generate crowds at concerts. Major classic rock albums include The Beatles' Revolver and The Rolling Stones' Sticky Fingers. While classic rock declined in popularity due to newer genres like punk and new wave in the late 1970s-early 1980s, it still maintains a fanbase through documentaries, radio stations, and websites focused on the genre.
