Lzzy Hale, whose band Halestorm was one of the groups chosen as a supporting act for the July 5 show, in Birmingham, England, tells PEOPLE in this week’s issue that her memories of Osborne — who died on July 22 at age 76, just two weeks after the show — will forever remind her of the power of music.

Late rock legend Ozzy Osbourne's July 5 farewell performance generated about $190 million for children's hospitals and Parkinson's research charities.

Osbourne preceded the Black Sabbath performance at Back to the Beginning with a set featuring members of his past solo bands. He played "I Don’t Know," "Mr. Crowley," "Suicide Solution," "Mama, I’m Coming Home" and "Crazy Train."

Ozzy Osbourne's "final moment" at his farewell concert has gone viral on social media. The Black Sabbath frontman, known as the "Prince of Darkness," died on Tuesday at the age of 76.

Zakk Wylde, who spent decades playing guitar for Ozzy Osbourne, spoke about the last time he saw the metal legend and their long friendship.
