Miles Mykkanen, a winner of the 2019 Metropolitan Opera National Council Auditions, comes home to Michigan’s western Upper Peninsula on the southern shores of Lake Superior as the impresario of a brand-new festival. The pandemic has dashed much of his advance planning, but the final week of programming remains, offering the concert “Broadway Under the Stars” and a recital by the talented Mr. Mykkanen himself, a tenor whose timbre, technique, and personable manner hark back to heartbreakers from the Old World. —M.G.
