I believe Black Sabbath is ranked as #1 in certain polls as the most influential band to the metal genre, with Priest 2nd. Which of course I disagree, Judas Priest should be #1, but that's just in my world and opinion. These two bands are more Heavy Metal, than bands of the more modern sub-genres of metal. Ozzy Osbourne's solo career is probably my favorite of all of the others, from the early 80s and so on. He's produced some great guitarist through the years, and each one has their own unique style that is different from each other.
