At a point where a good many of his peers have shifted into coasting mode,
Jeff Tweedy continues to tinker under Wilco's hood, grafting on and sawing off seemingly entrenched elements with surprising ease. And while the changes manifested on
A Ghost Is Born are more evolutionary than revolutionary, the fact that Tweedy continues to see his band as a work in progress makes for plenty of welcome surprises.
A Ghost Is Born has a few things in common with its critically acclaimed predecessor,
Yankee Hotel Foxtrot, chiefly the willingness to ignore the strictures of standard arrangement (not to mention the clock on the wall). Those two elements dovetail beautifully in the ten-minute "Spiders (Kidsmoke)," on which Tweedy splices a snaky
Television-styled guitar figure onto an insistent Kraut-rock rhythm to great effect. There's an overall uptick in instrumental freakouts, both extended and compact: After a short, simple intro, the 15-minute "Less than You Think" segues into a static lullaby that owes as much to
Terry Riley as Tweedy's embryonic work did to the
Carter Family, while the initially lulling "At Least That's What You Said" culminates in a fusillade of ragged melodic shards that screams "duck and cover." That aggression is offset by a lingering delicacy, one that lends an appropriately wraithlike tone to songs like the fine-spun "Muzzle of Bees" and the deceptively jaunty "Hummingbird," which kicks off with some sweet keyboard/strings interplay that could pass for the theme from some hazily remembered '70s TV series.
A Ghost Is Born may not be the perfect summer soundtrack, but it's laced with sonic ideas that will last long after those tan lines fade into memory.
