Týr announced on 12 May 2013 via their official website as well as their Facebook, Twitter and Myspace pages that they had parted ways with long-time drummer Kári Streymoy, owing to the back injury he had received in 2008 which had affected his drumming. On May 15, 2013, they announced that renowned metal drummer George Kollias will record drums for their seventh album Valkyrja. Amon Djurhuus enters temporarily in the band, once again, for the tour with Finntroll between September and October 2013.
