Metallica have postponed a forthcoming tour of Australia and New Zealand so that frontman James Hetfield may enter an addiction treatment program. “As most of you probably know, our brother James has been struggling with addiction on and off for many years,” Metallica wrote tonight in Instagram post. The band added: “He has now, unfortunately, had to re-enter a treatment program to work on his recovery again.” Find Metallicas full statement in the below Instagram post.

Metallica’s tour was originally scheduled to begin October 17 in Perth, Australia, and wrap up November 2 in Auckland, New Zealand. The band have guaranteed a full refund for ticket holders.

Update, February 24: Hetfield announced that Metallica has been forced to cancel appearances at Sonic Temple Festival in Columbus and Louder Than Life in Louisville. Hetfield said the dates have been called off so he can focus on his therapy. “Looking on the brighter side, my therapy is going well,” he wrote. “It was absolutely necessary for me to look after my mental, physical, and spiritual health.”
