Black Sabbath will make a huge return in June with 13, their first album with Ozzy Osbourne, Tony Iommi and Geezer Butler since 1978's Never Say Die! What's more, today marks the 43rd anniversary of the original U.K. release of their debut album, Black Sabbath, and the band is celebrating by releasing this glimpse into their studio as they record the new album. "You can't always repeat what you've done, you've just got to go on," says Butler in the clip. "It'll be today's version of where it was 40 years ago, I suppose."
"It's different altogether now," Butler adds later. "We have much more of a thing going than what it was [in those] days."
Ozzy also feels invigorated with their current incarnation, which features Rage Against the Machine drummer Brad Wilk as replacement for Bill Ward (who dropped out of the reunion in May). "I wanted to sound current," says Ozzy, "yet still have that Sabbath vibe." 13 will be released in June and is produced by Rick Rubin.This article originally appeared on Rolling Stone: Black Sabbath Offer a Peek Inside Their Studio
