Pantera had performed earlier this month at the Back to the Beginning reunion concert in Birmingham on July 5 - the historic Black Sabbath event that saw Osbourne reunite with guitarist Tony Iommi for the final time. The show marked Ozzy's last public performance.

Pantera has announced that they are rescheduling and canceling some of their tour dates to 'mourn' Ozzy Osbourne's death.

In light of this profound loss, we need time and space to grieve — to be with our families, our crew, and each other as we process and honor the life of someone who meant so much to us,” they write.
