We’re heartbroken to say that our upcoming tour with Sum 41 in South America just got cancelled. We just found out our friend Deryck Whibley from Sum 41 needs focus on recovering from a medical condition. Health comes before anything else, especially when bands spend so much of their time out on the road. We wish him all the best and we’re working hard to get back on the road as soon as possible, we wish this was in our hands and hope to see you soon.
