I've been a big Wilco fan ever since the release of their 2002 album, "Yankee Hotel Foxtrot." Before that, I really didn't understand any of their work. Too artsy, too intellectual. It was on "Yankee Hotel Foxtrot" where, uh, Jay Bennett's presence became more apparent. I think "A Ghost Is Born" was the group's undisputed masterpiece. It's an epic meditation on intangibility. At the same time, it deepens and enriches the meaning of the preceding three albums.
