Robert Earl Keen’s second live album, No. 2 Live Dinner, is supposed to signal his transition from Lone Star folk singer to roadhouse rocker. In goosing 13 of his best-loved songs (”Gringo Honeymoon”) and serving up two new ones, Keen sounds livelier but never erupts into a powerhouse. That’s okay — his sandpaper-and-sawdust vocals are welcome anytime.
