Success 2012: Ozzy Osbourne, "Godfather of Heavy Metal". Ex-lead singer of the pioneering English band Black Sabbath. Osbourne has achieved multi-platinum status as a solo artist and with Black Sabbath and has sold over 100 million albums worldwide

John Michael "Ozzy" Osbourne (born 3 December 1948) is an English heavy metal vocalist and songwriter, whose musical career has spanned over 40 years. Osbourne rose to prominence as lead singer of the pioneering English band Black Sabbath, whose dark and hard sound helped spawn the heavy metal genre. Due to Sabbath's dark style, Osbourne became known as the "Prince of Darkness". Osbourne is also known as the "Godfather of Heavy Metal".
In the early 2000s, Osbourne's career expanded when he became a star in his own reality show The Osbournes, alongside wife/manager Sharon and two of their three children, Kelly and Jack. A documentary about his life and career, God Bless Ozzy Osbourne, premiered in April 2011 at the Tribeca Film Festival and was released on DVD in November 2011. Osbourne has achieved multi-platinum status as a solo artist and with Black Sabbath and has sold over 100 million albums worldwide.
In late 1967, Geezer Butler formed his first band "Rare Breed" with Osbourne. The band played two shows then broke up. Separated for a time, Osbourne and Butler reunited in Polka Tulk Blues along with guitarist Tony Iommi and drummer Bill Ward. They renamed themselves Earth, but after being booked in error instead of a small-time English circuit band with the same name, they decided to change their name again. They finally chose the name Black Sabbath in early 1969 based on a film directed by Mario Bava, starring Boris Karloff. The band had noticed how people enjoyed being frightened, and, inspired, Iommi and his partners decided to play a heavy blues style of music laced with gloomy sounds and lyrics. While recording their first album in a castle, Geezer read an occult book and had a dream of a dark figure at the end of his bed. Butler told Osbourne about the dream and together they wrote the lyrics to "Black Sabbath", one of their first songs in a darker vein.
Despite only a modest investment from their U.S. record label Warner Bros. Records, Black Sabbath met with swift and enduring success. Built around Tony Iommi's guitar riffs, Geezer Butler's lyrics, Bill Ward's dark tempo drumbeats, and topped by Osbourne's eerie vocals, early records such as their debut album Black Sabbath and Paranoid sold huge numbers, as well as getting considerable airplay. Osbourne recalls a band lament, "in those days, the band wasn't very popular with the women".
Just five months after the release of Paranoid the band released Master of Reality. The album reached the top ten in both the United States and UK, and was certified gold in less than two months. In the 1980s it received platinum certification and went Double Platinum in the early 21st century. Reviews of the album were unfavorable. Lester Bangs of Rolling Stone dismissed Master of Reality as "naïve, simplistic, repetitive, absolute doggerel", although the very same magazine would later place the album at number 298 on their 500 Greatest Albums of All Time list, compiled in 2003. Black Sabbath's Volume 4 was released in September 1972. Critics were again dismissive of the album, yet it achieved gold status in less than a month. It was the band's fourth consecutive release to sell one million copies in the United States.
In November 1973, Black Sabbath released the critically acclaimed Sabbath Bloody Sabbath. For the first time, the band received favourable reviews in the mainstream press. Gordon Fletcher of Rolling Stone called the album "an extraordinarily gripping affair", and "nothing less than a complete success". Allmusic's Eduardo Rivadavia call the album a "masterpiece, essential to any heavy metal collection", while also claiming the band displayed "a newfound sense of finesse and maturity".The album marked the band's fifth consecutive platinum selling album in the US. Sabotage was released in July 1975. Again there were favourable reviews. Rolling Stone stated, "Sabotage is not only Black Sabbath's best record since Paranoid, it might be their best ever."Allmusic was not so favourable. They noted that "the magical chemistry that made such albums as Paranoid and Volume 4 so special was beginning to disintegrate".Technical Ecstasy, released on 25 September 1976, was also met with mixed reviews. AllMusic gave the album two stars, and noted that the band was "unravelling at an alarming rate".

In 1980, under the management of Osbourne's then girlfriend (later wife), Sharon Arden, the Ozzy Osbourne Band formed again as The Blizzard of Ozz. The first line-up of the band featured drummer Lee Kerslake (of Uriah Heep), bassist/lyricist Bob Daisley (of Rainbow and later Uriah Heep), keyboardist Don Airey, and guitarist Randy Rhoads (of Quiet Riot). The record company would eventually title the record Blizzard of Ozz credited simply under Osbourne's name. Co-written with Daisley and Rhoads, the album brought Osbourne considerable success on his first solo effort. The album sold very well with hard rock/heavy metal fans. Though it is generally accepted that Osbourne and Rhoads started the band, bassist Daisley later claimed that he and Osbourne formed the band before Rhoads joined. Blizzard of Ozz is one of the very few albums amongst the 100 best selling albums of the 1980s to have achieved multi-platinum status without the benefit of a Top 40 single. As of August 1997, it achieved Quadruple Platinum status according to RIAA. The album is known for the globally recognised singles "Crazy Train" and "Mr Crowley", and fan favourites "Goodbye to Romance" and "Revelation (Mother Earth)". Although Kerslake and Daisley are credited as the studio musicians for The Blizzard of Ozz, the touring band in support of the album consisted of Osbourne, Rhoads, Rudy Sarzo (Bass) and Tommy Aldridge (Drums).
