The band's 10th studio album is an about-face from the raucousness of last year's release, Star Wars. They've largely put away their rock-star electrics and pulled out their acoustic guitars. Despite the mellower sound and the playful (or perhaps dismissive) album title, the lyrics explore fear, loathing, and being haunted by a lack of identity. But Wilco presents the dark subject matter with a spoonful of tuneful musical sugar. There's a reason why frontman Jeff Tweedy calls this album "joyously negative."
