Who is it

I´m going to start with that I will call the person the singer. This person is famous for surviving through all this years. You see he´s been taking so many drugs that a normal person would have died but he didn´t. But he is also a famous singer. He started he´s career in a band that first called themself the Earth but then changed name to Black sabbath. Black sabath was famous in the 1970´s. They did four top hit albums and had many hits at the time but in the end after six albums they kicked out the lead singer in other words the man who I´m trying to tell you about. After he was kicked out of Black sabbath he started a solo career and played with the famous incredibly skilled guitarist Randy Roads. Randy Roads unfornately died in an airplain accident wile he was doing he´s second tour with the singer. But the singer didn´t give up. He found another great gutiarist named Zack Wild that nowadays plays in a band called Black Label Society, I saw them live this summer at sweden rock by the way. With the new guitarist he had a number of hits like Shot in the dark, Mamma I´m coming home and Dreamer but 2001 he said that he was going to focus everything on black label socyeti. But the singer still diden´t quit. In 2010 he did a new album that had one hit called Let me hear you scream, I saw him live at sweden rock by the way. Nowadays he´s called the Prince of darknes.
