The legendary Black Sabbath frontman died just 17 days after his July 5, 2025, farewell performance in Birmingham, England.

The 10-hour farewell concert, titled "Back to the Beginning," featured Osbourne alongside Black Sabbath bandmates Geezer Butler, Tony Iommi, and Bill Ward, with appearances from numerous other artists. Osbourne was lifted onto the stage seated on a throne and performed hits like "Crazy Train" while remaining seated. "It is with more sadness than mere words can convey that we have to report that our beloved Ozzy Osbourne has passed away this morning," his family stated at the time of his death. "He was with his family and surrounded by love."

Ozzy Osbourne's death certificate listed cardiac arrest, acute myocardial infarction, coronary artery disease, and Parkinson's disease as the causes. His wife, Sharon Osbourne, also shared her final moments with the rocker, recounting how he woke her early on the morning of his death, asking for a kiss and a tight hug. She recalled hearing screaming and attempts to resuscitate him, but knew instantly he was gone. Sharon Osbourne admitted that her grief was overwhelming, leading to struggles with functioning and regrets about their final exchange. "If only I'd have told him I loved him more. If only I'd have held him tighter," she said tearfully.
