I was around in the 70s Violet. I was between 2 & 1/2 (1970) to 11 & 1/2 (Dec. 1979). I remember vividly my brothers,when we lived in California (77-80),making friends who got them into groups like Sabbath & other loud acts of the past 8 to 10 years.
My Mother liked some of it but just not played so loud or when they said bad words. My Grandmother (age 68 to 70 then) flat out hated it all! I laugh when I think back on how she called Van Halen, "Van Heflin" (an old Hollywood actor).
LOL:D
As for Sabbth's music,it's goofd,it's loud,it was and still is controversial,like Ozzy himself is. I guess they did influence the past 2 generations (or is it 3?)

I never was a "metal head" anyway! :D
