There are only 2 original heavy metal bands…Black Sabbath as the creators, and Judas Priest as the innovators. First coming, second coming…then the rest. Not minimizing any band or their contribution, I like all metal and most of its sub-genres as well as recognize the many icons that have appeared, disappeared, and stayed with us long after death, this is not a “this band is better than that band” statement…just saying…IMHO…heavy metal is Black Sabbath, then its Judas Priest, then its all the rest. What say you disciples of the watch? Rock on.
