They are recognized by metal fans and metal historians as being the band that introduced the "Sign of the horns" to rock, metal and pop culture (as seen on their 1969 debut album release Witchcraft Destroys Minds & Reaps Souls, which has an opening track called "Black Sabbath")".https://officinebrand.it/wp-content/uploads/2017/02/CBack.jpg:-)
