Finnish rock cello quartet Apocalyptica has issued the following statement:

“We wanted to let you know that sadly we are having to reschedule the current run of [North American] dates [which were scheduled to begin on November 25 in Orlando] to the beginning of March 2011. This is due to issues with Perttu‘s [Kivilaakso] health; we have taken the advice of several doctors before making this decision.

“We are working on all details and more information for you right now, and of course we will keep you fully informed! We apologize for any inconvenience this may have caused our fans and look forward to returning to health and touring in 2011.”
