The kind of music that changed the 1960s was C- Counterculture.

Counterculture was an anti-establishment phenomenon that developed between the mid-1960s and the mid-1970s in the UK and then spread to the United States and the Western World. This movement marked the first cultural-revolution that used multiple media platforms to urge the society to take action and reject the norms of the previous decade, so as to express their opinion regarding the US intervention in Vietnam, sexuality, civil rights, and more.
