Diary of a Madman

John Michael "Ozzy" Osbourne is an English vocalist, whose musical career has spanned over 40 years. Osbourne rose to prominence as lead singer of the pioneering English heavy metal band Black Sabbath, whose radically different, intentionally dark, harder sound helped spawn the heavy metal genre. In his subsequent solo career Osbourne achieved a multi-platinum status in addition to the one he had earned with Black Sabbath. These things are what... led Osbourne to become known as the "Godfather of Heavy Metal". It was during his Sabbath days that, due to their dark style of music, Osbourne became known as the "Prince of Darkness". Osbourne has over 15 tattoos, the most famous of which are the letters O-Z-Z-Y across the knuckles of his left hand. This was his first tattoo, created by himself as a teenager with a sewing needle and pencil lead. In the early 2000s, Osbourne's career expanded to a new medium 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.

Heavy metal is a genre of rock music that developed in the late 1960s and early 1970s, largely in the Midlands of the United Kingdom and the United... States. With roots in blues rock and psychedelic rock, the bands that created heavy metal developed a thick, massive sound, characterized by highly amplified distortion, extended guitar solos, emphatic beats, and overall loudness. Heavy metal lyrics and performance styles are generally associated with masculinity and machismo. The first heavy metal bands such as Led Zeppelin, Black Sabbath and Deep Purple attracted large audiences, though they were often critically reviled, a status common throughout the history of the genre. In the mid-1970s Judas Priest helped spur the genre's evolution by discarding much of its blues influence; Motörhead introduced a punk rock sensibility and an increasing emphasis on speed. Bands in the New Wave of British Heavy Metal such as Iron Maiden followed in a similar vein. Before the end of the decade, heavy metal had attracted a worldwide following of fans known as "metalheads" or "headbangers".
