Ozzy will release a solo career retrospective titled "Memoirs Of A Madman" on October 7.

While it remains unclear whether BLACK SABBATH will record another studio album, Osbourne appears certain to continue with his solo career. Ozzy's touring guitarist, Gus G., told Noisefull in a recent interview, "Ozzy wants to do another solo album, that's for sure. As far as I know, he has a contract for three more solo albums, so I don't know when he will finish them, if he'll do them and if I'm going to be a part in it, but I certainly know that he wants to do one more solo album."

Ozzy's last solo studio effort was 2010's "Scream".

His first album under the SABBATH banner in 35 years, "13", came out in June 2013 and topped both the U.S. and U.K. album charts, later winning a Grammy Award as well.

There's no timeline on when Ozzy might record his next solo effort. Ozzy has indicated that he would also like to record a new SABBATH album.
