John Michael "Ozzy" Osbourne (December 3, 1948 – July 22, 2025) was an English singer-songwriter, whose career has now spanned five decades. Osbourne rose to fame as the lead vocalist of British heavy metal band, Black Sabbath, until he temporarily left the band in 1977, and was temporarily replaced by Dave Walker. From 1977-1978, he made his first attempt at a solo career with former Necromandus members Barry Dunnery, Dennis McCarten, and Frank Hall, until by request by his former band members, he returned to Black Sabbath in 1978. After he was fired from Black Sabbath in 1979, he started his second attempt at a solo career with former Quiet Riot guitarist Randy Rhoads, former Rainbow bassist Bob Daisley, and former Uriah Heep drummer Lee Kerslake, and the band was called under the name "Blizzard of Ozz".
