The music world is reacting to the news that Ozzy Osbourne has died. Osbourne’s surviving bandmates in Black Sabbath led the way with a simple message: “Ozzy Forever.”

“He was a dear friend and a huge trailblazer who secured his place in the pantheon of rock gods – a true legend,” wrote Elton John, who featured on the title song of Osbourne’s Ordinary Man. “He was also one of the funniest people I’ve ever met. I will miss him dearly. To Sharon and the family, I send my condolences and love.”

Pearl Jam’s Mike McCready, a collaborator on Osbourne’s final album, Patient Number 9, shared: “Sad to hear Ozzy died today. When I was in high school I discovered Sabbath. ‘War Pigs’ was terrifying and mesmerizing at the same time. It was Ozzy’s voice that took me away to a dark universe. A great escape. Then when The ‘Blizzard of Ozz’ record came out I was instantly a fan. Randy Rhoads was an influence on me to play lead guitar. Luckily I got to play on the song ‘Immortal’ on the last record. Thanks for the music, Ozzy it makes our journey in life better.”
