Ozzy Osborne has confirmed that a new album and tour has been agreed for Black Sabbath.
It had been thought the band's last album, 13, released last year and tour might have been their last. The album broke the record for most years between number ones, coming 43 years after their last.
But speaking to Metal Hammer, Osborne said:
Although no timescale has yet been set the singer said: "It'll be sooner rather than later."
University students will enjoy music lessons from a heavy metal legend after Black Sabbath's Tony Iommi was unveiled as their new professor.
The founding member of the the legendary heavy metal group was awarded an honorary doctorate by Coventry University in November last year.
During a recent visit the guitarist spent the afternoon talking to students and staff and answering their questions about his illustrious career. And the 65-year-old rocker got on so well there he has now been named as a professor of music for their Department for Performing Arts.
The rock icon will teach students song-writing and composition skills when he takes up the role in the Autumn.
Black Sabbath are topping the bill at an outdoor show in London's Hyde Park this summer - and they hope they will get royal approval.
The veteran rock group is the latest headline act to be announced for the British Summer Time festival, and will play the event's opening night on July 4.
Osbourne reminisced that when he first went to London he was impoverished and "spent the advance I got for the first album on a new pair of shoes and some Brut aftershave".
"Returning almost 50 years on we are doing a bit better for ourselves, so I may even splash out on some new aftershave before taking to the stage at Hyde Park ... We are beyond honoured to be allowed to put on a show and hope that the royals will enjoy it," he added.
Heavy metal veterans Black Sabbath crowned their comeback with a double win at a top rock awards event.

Birmingham rock legends Black Sabbath have announced the title of their new album - 13.
