A Christmas with the Rocke Brothers performance is planned at 6 p.m. Sunday at First Covenant Church in Iron Mountain. Brothers Micah, Levi, Ethan and Matthew, based in northeastern Wisconsin, grew up singing together along with their family of 13. The four brothers have been together as a quartet since 2014. They bring a diversity of styles to their concerts, including Southern gospel, acapella, Christmas classics and familiar carols. Each concert is filled with stories, humor and reminders of what the season is all about.
