In a spiral, M. Shadows got a viral infection after the band’s European tour. As his voice got worse, the band eventually had no choice but to announce that their End Of The World Tour is canceled in full.

In a letter the band shared on their page, Shadows apologizes for the short notice and assures fans he did everything in his power to stay well.

“Decisions like this weigh on me very heavily,” Shadows says. “It’s a tour I was looking forward to very much. I want to apologize to the fans who have spent their time and money booking travel arrangements and accommodations. I also want to apologize to our crew and the other bands who were depending on this tour.”

Currently, the damage done to the frontman’s vocal cords left him with no singing voice. The vocalist says it is due to a blood blister that formed on his vocal folds. You can read the full letter here.

Tickets for tour dates can be refunded through ticket holders’ point of purchase. For information regarding Impact Festival and Heavy Montreal, the band urge ticket holders to visit the festivals’ respective websites.
