Ex-Black Sabbath maestro Ozzy Osbourne has revealed that he is halfway through finishing a brand new album, despite releasing his 12th LP Ordinary Man in February.

His next album is set to feature guest appearance from Robert Trujillo and Foo Fighters' Taylor Hawkins.

The heavy rocker has joined forces once again with Andrew Watt, with the producer claiming that he and the Black Sabbath star are well on their way to completing the project after he was forced to halt the recording process when he tested positive for Covid-19.

"We're about halfway through," Watt told Guitar World. "But, you know, it's been hard with Covid and everything to keep him (Ozzy) safe. We all test every day before we work and it's just me, Ozzy and my engineer. So it's taken a little longer this time, but it's cool because the last one was made in this, like, swift love affair of passion, like, 'Oh my God, this is incredible!'"

"This time everyone's moving a little slower and we're taking a little more time," Watt added.

"And the songs, there's some songs on there that are, like, eight or nine minutes long that are these really crazy journeys. I'm really excited about it."

Watt reveals there's "a bunch" of famous musicians and rock veterans who will appear on the album.

"I can't say for sure until the end, but I started doing a bunch of basic tracks with Chad (Smith) and Robert Trujillo, who used to play in Ozzy's band. And Taylor Hawkins also came in and played a bunch on the record as well, which adds a different flair. I think it's so cool for a rock fan to be able to listen to half an album with Chad Smith on drums, and then you flip it over and you get to hear Taylor Hawkins."

Osbourne announced in November that his rescheduled UK and European dates of his ‘No More Tours 2’ tour will now take place in 2022.
