Ozzy Osbourne has been remembered as a “pioneer,” a “fearless talent” and a “dear friend,” in an outpouring of tributes from fellow musicians and his former Black Sabbath bandmates following his death on Tuesday at the age of 76.

Osbourne, who suffered from advanced Parkinson’s disease, performed at the final concert without any issues. Seated on a bat-winged throne, he sang five solo songs and four Black Sabbath songs, ending his final show of his career with the 1970 classic "Paranoid.”
