It’s a simultaneously cool and humid Brooklyn night in the middle of September and it seems as if Mother Nature can’t decide whether or not she wants to let summer live longer or finally transition into fall. The outfits spotted in line outside the Music Hall of Williamsburg reflect this confusion. As people begin to hold their spots in front of the venue nearly an hour before doors are set to open, there’s a clear thread between many of these outfit choices. Traces of black and yellow stick out in the midst of the crowd as dedicated fans proudly display their Sonder merchandise.
