Back then, Ozzy was the singer in Black Sabbath, and they meant business. In an era when it seemed possible to measure a band's musical prowess by how 'heavy' they were, they didn't come any weightier than Black Sabbath. This biography tells the story of how they made that dream come true - and how it then turned into a nightmare for all of them.
