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.

Johnny Depp surprised fans by joining Alice Cooper's July 25 concert in London to perform Black Sabbath's hit "Paranoid" as a tribute to Ozzy Osbourne, who died three days prior at the age of 76.
