The black Keys have reportedly canceled a series of European tour dates, as well as several dates in Australia and New Zealand, citing exhaustion. "An arduous year of touring and promotion has darned the band and necessitated time off," a statement on the band's website reads. "Dan [Auerbach] and Patrick [Carney] wish to thank all of you who have shown such incredible support since the release of 'Brothers' and have helped make the album a success."
