That's right! MARK YOUR CALENDAR! Your eyes didn't deceive you above either. Zakk Wylde is joining him too.

You'll probably recall that their best work together was No Rest for the Wicked, Live & Loud, Ozzmosis and many more. They recorded Black Rain in 2007, and that was the last time they teamed up. They found each other in 1987.

Tickets for this show go on sale Saturday, June 24 at 10am.

Don't miss this opportunity! You never know when you'll see Zakk and Ozzy together again! It's a must see show.
