While this album is decent, and represents a welcome return to the concept of melody, Jeff Tweedy is still parked firmly in the back seat when it comes to writing and creating innovative, interesting and thought-provoking music, when put alongside former Uncle Tupelo founder Jay Farrar.
Yankee Hotel Foxtrot (or "YHF" as cooler kids than myself call it) was rejected by Wilco's label with good reason - it is a disjointed, nearly unlistenable album that has only received critical acclaim as a result of the "David vs. Goliath" (starring Tweedy in the role of David) persona that Tweedy et al. have now been branded with.
Some of Wilco's work, after Tweedy's departure from Uncle Tupelo, and Tweedy's work in side projects such as Golden Smog and the Minus 5, is simply fantastic. "Ghost" is not quite up to par with such material, but it seems to represent a return to apparently unpopular concepts such as melody and listenability.
While "Ghost" is worth a listen, and probably a purchase, one's money is better spent on Farrar's works such as his Son Volt triumphs, and even his more fringe solo efforts. If it's "innovative" or "interesting" music you are looking for in the "alt-country" genre, that is the place to find it.
