I’m really surprised nobody has mentioned Helen Reddy and particularly her song “I am Woman”. It was pretty well the feminist national anthem in the 1970’s. I’m sure a lot of younger women nowadays don’t care or are even aware about the feminist movement of that era because they can now take everything for granted. The 60’s and 70’s were definately a time of major social change. Of course some of the radical feminists back then were totally over the top.

I had to look it up 
My mom moved to NYC when she was 19, met my dad, married, and they promptly got transferred overseas (Liberia, South Africa, and Australia). She was married to him for eleven years and was only able to leave him when they were back visiting the states when I was a little less than 2, as he controlled her by making her keep track of every penny she spent. Every penny. I’ve seen the sheets. Whoa. He would not let her work, and she was, literally, trapped. Trapped in a very affluent lifestyle, mind you, but trapped. When she left him, she was a single mother in Iowa in 1976, with a young child and no work experience. To say she “embraced” the feminist movement would be an understatement.
She ran for state legislature when I was 5, against a republican incumbent and only lost by 500 votes. She then worked as a lobbyist for many groups, but, most notably for Planned Parenthood. I grew up surrounded by strong, outspoken, “militant,” “radical” feminists. When she remarried when I was 10, she still kept completely separate money–and didn’t take money from him–and continues to do so even today.
As awesome as she was (is), she never listened to music. Weird. I can’t imagine my life without music. I listen to it all day, every day. Anyway, I didn’t really “discover” music until the fifth grade, and then I was just into pop–Madonna, Prince, etc. So I “missed out” on a lot of music from that revolutionary period. I certainly went back to that period, as a teenager (and on), but I was listening to different artists/bands from that period;)
