Wilco is a little like baseball, in that you probably know the rules, but the die-hard fans see skill and nuance that are impossible to convey to the casual crowd. Jeff Tweedy and company have become a full-blown American institution, and their fans are tracking stats, keeping up with the band on a micro level. At a time when the music landscape is filled to capacity with tiny genres and outsized attitudes, it's comforting that Wilco exists, continuing to make music that feels like it's been around forever and will find its audience long after current trends burn out.
