Black Sabbath may be rock and roll legends, but no one could have predicted the success that their latest album, 13, would achieve. The band currently features original members Ozzy Osbourne, Tony Iommi and Geezer Butler, and for the first time in Black Sabbath's long history, they have landed a number one album on the Billboard 200 chart. 13 sold 155,000 copies in its first week, beating Daft Punk’s Random Access Memory by over 100,000 units. "To finally have our first Number One album in the U.S. is another incredible milestone for Black Sabbath. Thank you to all of our fans for their support and loyalty," Ozzy said.

While this may mark their first number one album, it's not the first time that the group has been on the charts. 1971's Master of Reality made it to number eight back in the day and Ozzy's 2007 solo album Black Rain peaked at number three when it was released.

Black Sabbath isn't just tearing up the charts here in the States though. Across the Atlantic in their native England, the band also claimed the number one spot for the first time since 1970's Paranoid, setting the record for the longest gap between number one albums. Butler stated, "I'm absolutely stunned. Thank you all worldwide for being the best, and most patient, fans ever."

Meanwhile Iommi, who is undergoing cancer treatments, said "The news is absolutely amazing -- we couldn't have imagined this would happen. We have the greatest fans."

The band is set to kick off a North American Tour in support of the album beginning July 25 in Houston. Check out a complete list of dates here.
