British singer and musician Ozzy Osbourne is called the "Godfather" of what musical genre?

The Godfather of Heavy Metal, Ozzy Osbourne is the man whose involvement in the music industry led to the discovery and development of the Heavy Metal as a musical genre. A founding member of the legendary Black Sabbath, Ozzy has had an instrumental role to play in the branching out of Rock into an art that was neither heard and interestingly nor sought. Well, the heavy metal wasn't so much like art as the parade of aggression.

The Black Sabbath started off as a Rock band but the transition to dark heavy metal was inevitable given Osbourne’s presence in the group. That brings up why the Black Sabbath are the instigators of heavy metal music. The band was too loudly good at what they did that they developed an unparalleled reputation based on their style.

The machismo group produced some of the loudest and fiercest songs of the era. Once you listen to songs like Children of the Grave and War Pigs, you just can't unlisten them.
