Stop us if you've heard this one: Country-fried underground rap act rockets into outer space on an interstellar second studio LP. There are a few more shared coordinates between OutKast's ATLiens and Big K.R.I.T.'s Cadillactica (Def Jam) — see the 808-bumped Mason-Dixon funk rumbles and Cadillac-as-flying-DeLorean mode of travel — but also one major deviation: K.R.I.T. (King Remembered In Time; Earth name Justin Scott) is a product of hip-hop's mixtape era, so what appeared to many listeners as a sophomore explosion was actually a slow-cooked 11th release. (If Live From the Underground seemed to hit unusually hard for a debut, there's your answer.) In that context, Cadillactica plays more like a mid-career freakout — call it Showtime at the Apollo Program. As with Big Boi and Andre 3000, K.R.I.T.'s universal scope obscures no details: "My Sub Pt. 3 (Big Bang)" pays homage to low-frequency modulation in both words and music ("My trunk knock like Jehovah's Witness"); "King of the South" reigns as a Mississippi-burning origin story ("Born and raised where the rebel flag hang from the slaves"), righteous claim to the throne and backup track record embalmed in wax; and "Soul Food" serves up nostalgic Goodie Mob seconds ("Some get bruised and battered / Thrown away half-eaten as if their seeds never ever mattered"), an over-the-table, Southern-fable sequel slaking a long-forgotten craving. BJ the Chicago Kid opens. Tickets $28-$100.
