Gordon Kennedy follows in the footsteps of his revered guitarist father, Jerry, shaping the songs of roots luminaries with his well-honed fret-work. He adds Southern grit to Little Big Town’s “Boondocks” with a greasy slide performance and helps Reba McEntire groove with funky flourishes on “Can’t Even Get the Blues No More.” Meanwhile, he electrifies Faith Hill’s “What’s In It for Me” by switching seamlessly between boogying twang and rousing swells.
