Black Sabbath is mourning the Prince of Darkness.

After nearly 60 years of rock stardom — starting when the pioneering band, which formed in 1968 — Ozzy Osbourne died at age 76 on Tuesday, July 22. In the wake of his death, founding Black Sabbath members Tony Iommi, Bill Ward and Terence “Geezer” Butler shared heartfelt tributes to the group’s beloved, eccentric frontman.

“Where will I find you now?” Ward, 77, wrote on Instagram alongside what appears to be an old photo booth snap of himself and Ozzy. “In the memories, our unspoken embraces, our missed phone calls, no, you’re forever in my heart.”

The Black Sabbath drummer went on to share his “deepest condolences” to the late rock star’s wife, Sharon Osbourne, and their family, as well as his “sincere regrets to all the fans.”

“Never goodbye. Thank you forever. Bill Ward,” he finished the tribute to Ozzy, whom he described as his “dearest mate” in a post just months before the rocker’s death.

Butler, 76, and Iommi, 77, also shared tributes to the “Crazy Train” singer, in them expressing gratitude that Black Sabbath was able to reunite for a final performance in Birmingham, England shortly before Ozzy’s death. The concert marked his first with the band in 20 years.

“I just can’t believe it! My dear dear friend Ozzy has passed away only weeks after our show at Villa Park,” Iommi wrote on Instagram, referencing the July 5 gig, where Ozzy performed from a throne. (The rocker could no longer walk because of Parkinson’s disease, which he was diagnosed with in 2003.)

“It’s just such heartbreaking news that I can’t really find the words, there won’t ever be another like him,” the guitarist continued. “Geezer, Bill and myself have lost our brother. My thoughts go out to Sharon and all the Osbourne family. Rest in peace Oz. Tony.”

“Goodbye dear friend- thanks for all those years- we had some great fun,” the bassist wrote on Instagram. “4 kids from Aston- who’d have thought, eh?”

“So glad we got to do it one last time, back in Aston,” Butler finished. “Love you.”

Ozzy’s family announced his death in a statement shared with PEOPLE on Tuesday, July 22. “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,” they wrote. “He was with his family and surrounded by love. We ask everyone to respect our family privacy at this time.”

The metal icon leaves behind his wife Sharon, 72, and their three kids Aimee, 41, Kelly, 40, and Jack, 39. With his ex-wife Thelma Riley, he also shared kids Jessica and Louis, as well as her son Elliot.
