Lucinda Williams has always sounded wise and weary, but never has she seemed as comfortable with that role as on last year's Blessed. Williams achieved an alt-country masterwork early in her career with Car Wheels on a Gravel Road and wound up a household name somewhere around the considerably less-acclaimed West. These days she doesn't seem so concerned about the critics, the charts or her own hulking shadow, and this week we are the lucky host of a legend deep in the groove.
