Country star Kacey Musgraves suddenly canceled three tour performances without explanation, leaving fans both worried and annoyed. The first concert was set to serve as the opening night of her widely anticipated, 25-city “Middle of Nowhere” tour. The eight-time Grammy winner has yet to comment on the cancellations. Musgraves’ original Aug. 20 Chicago opening night, her Aug. 29 concert in Boston, and her Sept. 2 Brooklyn performance have all been axed. Some fans speculated on social media that the shows may have been canceled due to disappointing ticket sales.
