Rather than get into a rock-snob argument, it would be better to take a look at some of the great music Bennett made. Idolator has a must-watch collection of videos and links available here. Below is one of my favorites, from Yankee Hotel Foxtrot.
Jay Bennett's Music
Former member of Wilco Jay Bennett died in his sleep on Saturday. His time with Wilco -- both his significant contributions and his abrupt firing -- have been well-documented in the film I Am Trying to Break Your Heart. This Editor has always preferred Bennett-era Wilco -- especially Yankee Hotel Foxtrot -- to the later work from Jeff Tweedy, and he has a feeling many other listeners would agree.
