Black Sabbath had a stellar year in 2013. After 45 years of making heavy metal, the band scored their first No. 1 album in the United States with '13' and embarked on a long-awaited North American tour. What's next for Black Sabbath? According to vocalist Ozzy Osbourne, Sabbath will disband after one more album and touring cycle.

Back in September, Ozzy Osbourne claimed that one more album and tour was in Black Sabbath's future. Furthermore, Ozzy claims that Black Sabbath will be finished for good after the band releases its next album and hits the road one last time. He will then return to pursuing his solo career.

"A lot of people are asking me, with the success of the reformation of Black Sabbath, am I going to do any solo stuff any more? The answer is yes," Ozzy tells the Times-Picayune. "I am going to continue to do my solo stuff, but I can't do the two at the same time. This 'Memoirs of a Madman' package is to let everybody know that I haven't abandoned my solo career … I'm doing one more Black Sabbath tour, one more Black Sabbath album, and then we're disbanding the name, I believe. And then after that, I'll be doing my solo stuff."

Ozzy also shares the importance of ending Black Sabbath "on a happy note." And according to the legendary vocalist, the only sad note is that original drummer Bill Ward didn't perform on Black Sabbath's last tour. "It would be great for him to get it together and sort all the problems out for the next tour," Ozzy explains. "It would be a great way for the four of us to end such a wonderful experience of being Black Sabbath, and what we achieved."

Bill Ward has yet to comment on whether or not he'd be open to reuniting with Black Sabbath for one final goodbye to the fans.
