According to Blabbermouth.net, Black Sabbath frontman Ozzy Osbourne was named as the "greatest rock star in the world today" by the readers of the U.K. music magazine Kerrang!
In hailing Ozzy as the world's greatest rock star, Kerrang said: "In June he proved why he's the biggest musical star in the firmament. He sang like the devil himself [during an appearance at the U.K.'s Download festival with Black Sabbath]: wild power thundering from his mic."
Ozzy's Sabbath bandmate Tony Iommi also landed in the top ten, with Kerrang! magazine describing him as "a metal god with a backbone of pure steel".
Iommi was diagnosed with cancer late last year, forcing Sabbath to drastically curtail its touring plans and move the recording of the band's new album to London, so that Iommi could remain close to his doctors.
