John Michael "Ozzy" Osbourne (born 3 December 1948) is a British (British people) singer-songwriter, whose career has spanned four decades.

He rose to prominence as lead vocalist of pioneering British heavy metal (heavy metal music) band Black Sabbath, and eventually achieved a multi-platinum (RIAA certification) solo career between the early 1980s and mid 1990s which revolutionized the heavy metal genre.

In August 2008, Osbourne stated in USA Today that he intends to retire from his music career after two more albums.
