Black Sabbath's final album will be released next year, according to frontman Ozzy Osbourne.

The iconic metal band, who formed in 1968 and released their most recent album '13' in 2013, were originally meant to play their 'farewell' gig in Tokyo this November.

However, that gig has now been cancelled and Osbourne told a Brazilian press conference that the band would record/release another album and undertake one last tour.

"The plan is that next year we'll do the final Black Sabbath tour and album," Metal Hammer reports him as saying. "I'm not stopping... my wife spends all my money so I can't."

He said that several band members were reluctant to continue touring, but after the band part ways, he will continue with his solo career and is already "in the process of collecting stuff that I'm writing" for his next solo album.
