ZZ Top gone country? The idea is not as bizarre as you might think. As this tribute album by many of Nashville's top male performers demonstrates, the Texas trio's blues-rock tunes have always been informed by a rootsy, southern sensibility. The best tracks here are by the performers most comfortable with country blues—Willie Nelson's "She Loves My Automobile," Hank Williams III's "Fearless Boogie" and Dwight Yoakam's "I'm Bad, I'm Nationwide." And Lonestar's version of "Gimme All Your Lovin'" shows just how close the contemporary country band's raucous approach is to ZZ Top's, capturing the exuberant spirit and shameless hubris of the hirsute honorees.
