Paranoid is the 1970/71 release masterpiece of Black Sabbath. BS's innovation in rock led critics to first coin the term "heavy metal" to describe a genre of rock.
The band's name is often misunderstood. Band member Geezer Butler had an intense and upsetting apparition appear by his bed one night. He shared the experience with his band mates, resulting in their single, "Black Sabbath" . It had such a strong reaction from their fans, that the band, took it as their name.
It was not in admiration of black arts, but in their fear of it and their distress of the changes they saw in society around them.
Parnoid is considered their finest lp and starts off w/ their anti Vietnam war song :
1 War Pigs/Luke's Wall
3 Planet Caravan
4 Iron Man
5 Electric Funeral
