"I have mystical visions and cosmic vibrations." - Allen Ginsberg, America.
The 70s gave us musical artists such as Bob Dylan, Led Zeppelin, Patti Smith, Janis Joplin, Jimi Hendrix, The Doors, Lou Reed (I love his voice), Iggy Pop and The Stooges, David Bowie, The Beatles, The Who, Van Morrison, The Rolling Stones and many more great artists that have influenced current artists.
There was a large number of social movements including feminist movements, racial equality and gay rights movement.
The 70s was all about being who you were, poets were seen as one of the coolest people in society partly because they were similar to musicians except they were more modest about their talent.
You can't mention the 70's without mentioning Timothy Leary who some say the 70s wouldn't be what it is without him.
It was the non-conventional anarchist, them vs. us era.
