On their latest, Country Ghetto (Alligator Records), Floridian JJ Grey and his band Mofro call up an image of the south that’s defined not by geography but by a state of mind. Grey’s scarred, churchy vocals summon spirits like Hank Williams, James Carr, and Janis Joplin–all of whom are nearly as famous for their troubled lives as they are for their music–over a blend of Tony Joe White swamp funk and willfully brain-dead blooze rock seasoned with fatback horns. The songs’ hardened heroes don’t cry into their beer: they cozy up inside their prisons-, be they physical, social, or psychic. Take the drug-crazed protagonist of the gritty blues number “Tragic,” who continues to hustle his family and few remaining friends even as he sinks resolutely into oblivion. There’s no heaven here, just a cul-de-sac at the dark end of the street. New Monsoon and Backyard Tire Fire open. a 8:30 PM, House of Blues, 329 N.
