Luminaries of the music world mourned the death of Ozzy Osbourne at age 76, expressing affection and admiration for the heavy metal icon.

Elton John called the Black Sabbath frontman “a dear friend and a huge trailblazer” and “one of the funniest people I’ve ever met.” Nirvana said Black Sabbath was “the template for heavy rock.” Rod Stewart said he would “see you up there — later rather than sooner.”

Osbourne died Tuesday, just weeks after his farewell show. In 2020, he revealed he had Parkinson’s disease after suffering a fall.

Some reaction from various corners of the music world:
