Osbourne became a founding member of Black Sabbath in 1968, providing lead vocals from their self-titled debut album in 1970 to Never Say Die! in 1978. The band was highly influential in the development of heavy metal music, in particular their critically acclaimed releases Paranoid, Master of Reality, and Sabbath Bloody Sabbath. Osbourne was fired from Black Sabbath in 1979 due to alcohol and drug problems. He then began a successful solo career with Blizzard of Ozz in 1980 and has released 13 studio albums, the first seven of which received multi-platinum certifications in the US. He has since reunited with Black Sabbath on several occasions. He rejoined in 1997 and helped record the group's final studio album, 13 (2013) before they embarked on a farewell tour that ended with a 2017 performance in their native Birmingham. His longevity and success have earned him the informal title of the "Godfather of Metal
