And with tour plans now in tatters, Children Of Bodom frontman Alexi Laiho says he plans to use the time to sit down and write "angry sh*t." He says in a statement: "Our North American tour with Machine Head has officially been cancelled - this had nothing to do with me or COB.

"Sh*t f***in' happens, life goes on, and at least now we have an extra month and a half to write new COB sh*t. So instead of focusing on the negative, I'm gonna start to write music and it will be some angry sh*t."
