We’re quickly approaching the two-year anniversary of The Courtneys’ excellent sophomore album II, and they’re still touring in support of it. Their commitment is admirable, and the reward is hopefully a wealth of new fans eager to hear more from the Canadian trio. A stop at Thalia Hall in Chicago on Friday night actually marked the end of their tour with Cloud Nothings, so they celebrated with a wildly fun performance that perfectly balanced their winning charm and sadder sensibilities.
