In popular discussions about hard rock and its musical offshoots—metal and punk—Led Zeppelin reigns supreme. For example, VH1’s Top 100 Greatest Hard Rock Artists list places Led Zeppelin in the first spot with Black Sabbath, Jimi Hendrix, AC/DC and Metallica in the following positions. While I agree that Led Zeppelin is the most influential band across hard rock genres and in its infiltration into popular culture, I posit that Black Sabbath has played the bigger role in metal’s specific history.
The basic characteristics of metal—the dissonant vocals, the infernal riffs, the taboo lyrics—can all be traced back to Black Sabbath. Many a Gentile will find Ozzy Osbourne’s voice, along with his antics, to be crass and distasteful. A real metalhead will appreciate these qualities and the innate malevolence in his voice. The guy was born to be a metal singer.http://whitmanpioneer.com/arts/2014/01/30/makings-of-metal/
