The Prince of Darkness is also auctioning off a collection of abstract paintings he made with the help of chimpanzees to help the Save the Chimps foundation.

"Last Rites" also includes reflections on Osbourne's relationship with his wife Sharon, as well as his encounters with fellow rockers Slash, Bon Scott, John Bonham, and Keith Moon, and "the harrowing final moments he spent with Motörhead's Lemmy Kilmister," according to the press release.

Osborne recently performed his final concert on July 5 at the "Back to the Beginning" show, which featured one last Black Sabbath reunion with guitarist Tony Iommi, bassist Geezer Butler and drummer Bill Ward. Last Rites will be available Oct. 7, 2025, wherever books are sold.

Ozzy Osbourne went out with a bang. Following the rock icon’s death at age 76 on Tuesday, his Black Sabbath bandmate Tony Iommi told ITV News that he thinks Osbourne “held out” for the band’s July 5 farewell concert before he passed away.

In Birmingham, England, the singer’s hometown, fans paid tribute by leaving flowers, beer and tequila. The rapper Drake was there to pay his respects, too.
