R.I.P. Dio...

Although I will always be of the persuasion that Black Sabbath is only Black Sabbath when Ozzy is fronting them, I will say that metal would be different now had Ronnie James Dio never been on the scene. Even to this day songs like Holy Diver are covered over and over by bands like Killswitch Engage because they know where their roots are. R.I.P. Ronnie James Dio.
