Black Sabbath has released a behind-the-scenes video showing a glimpse of the making of their upcoming album, 13. The album will be the first from the band in 35 years, and was made with all of the original members of the group with the exception of Bill Ward.

The band took their time making the album because they wanted to get it right. Ozzy said, “If I had an album which blew Master Of Reality off the map, I'd be crazy not to do it. I don't want to put an album out, just for the sake of us four being on an album."

Things were also held up due to Tony Iommi’s cancer diagnoses and subsequent treatment. The band says that Iommi is doing great, and they’re planning to tour as much as they can this year.
