It occurred to me just after the new year that 2011 marked the 40th anniversary of the release of the Black Sabbath album “Paranoid” in the United States. Naturally, when Black Sabbath comes to mind, it’s easy to get lost in their immense legacy, especially on the heels on another milestone anniversary. While “Black Sabbath” put Osbourne, Iommi, Butler and Ward on the map, it was “Paranoid” that cemented them as one of the most unique and powerful bands in the world.
