No, it is not a new full song from Wintersun, but the band just announced that they and Swiss folk metallers Eluveitie will co-headline a North American tour this winter. They will be joined by Varg as well. The trek will celebrate Eluveitie's 10th anniversary and serve as Wintersun's introduction to North American shores. See the dates below.

Wintersun mastermind Jari Mäenpää commented: "We are very excited to tour US and Canada for the first time in November/December. We've had lots of requests from the fans before, but finally we are able to come there and kick some ass with new material from the Time I album and of course play the old stuff too! Hope to see you guys there. Let's make it special!"
