In a new interview with Michael Dwyer from The West Australian, BLACK SABBATH singer Ozzy Osbourne says the band's reunion album 13 is "a masterpiece."

"I heard the finished thing last week and I've got to be truthful with you, I was so bowled over by the way it sounded. If you liked Black Sabbath in the old days, you got to love 13. It's very heavy. It's very, VERY heavy.

"I'm my own worst critic," Osbourne adds. "Rather than the pluses I look for the minuses. And I haven't been this excited for an album in a long, long time. I can't remember the last time."
