Last week at the Greek theater, just prior to the Walkmen taking the stage, I overheard a man trying to explain the band's sound to his date. A number of adjectives and descriptors were tossed about -- 'torchy,' 'indie rock,' 'crooner,' 'jazz' -- which is fitting for a group that continues to defy easy genre construction, inhabiting their own space in contemporary music. When I got back that night I put this one on, "Paper House" --- a b-side from last year's become a member or log in.
