Other artists on the bill included Metallica, Guns N’ Roses, Slayer, Pantera and Alice in Chains, among others.

In the days following his death, Osbourne received an outpouring of praise from rock legends and fans alike. “THANK YOU FOR BLESSING THE WORLD w/YOUR KINDNESS & GREATNESS OZ – YOU BROUGHT LIGHT INTO SO MANY LIVES & MADE THE WORLD A BETTER PLACE – YOU LIVED w/THE HEART OF A LION – I THANK THE GOOD LORD EVERY DAY FOR BLESSING MY LIFE w/YOU IN IT,” his longtime guitarist Zakk Wylde wrote on Instagram. “I LOVE YOU OZ, BEYOND FOREVER, ZAKK XOXO.”

The singer was laid to rest during a private ceremony on July 30 after his funeral procession traveled through Birmingham and stopped at the Black Sabbath bench. Birmingham-based brass band Bostin Brass soundtracked the procession, covering Black Sabbath’s “Iron Man” and Osbourne’s solo hit “Crazy Train.”
