Ozzy Osbourne

John Michael "Ozzy" Osbourne (born 3 December 1948) is an English heavy metal vocalist, songwriter, and television personality. Osbourne rose to prominence in the early 1970s as the lead vocalist of the pioneering band Black Sabbath, whose dark and heavy sound has often been cited as key to the development of the heavy metal genre. Osbourne left Black Sabbath in 1979 and has since had a successful solo career, releasing 11 studio albums, the first seven of which were all awarded multi-platinum certifications in the US, though he has reunited with Black Sabbath on several occasions, most recently in 2011 to record the album 13, which was released in 2013. Osbourne's longevity and success have earned him the informal title of "Godfather of Heavy Metal".
