Whichever K.R.I.T. hits bigger for you — the self-mythologizing King Remembered In Time, tut-tutting would-be usurpers with trunk-rattling gall, skit-mocking skits and that real Southern-not-country/fish-and-grits shit; or just Justin Scott, humble mixtape underdog made amazingly good — his new magnum opus has a platter designed to speak directly to you. Odds are, both will. A low-frequency echo of 2011 highpoint Return of 4Eva, October release 4eva is a Mighty Long Time (Multi Alumni) also accidentally references the fate that befalls most mid-career double LPs — 22 tracks and 84 minutes is a mighty long time to hold modern attention spans. K.R.I.T. pulls it off by pulling together seven other superstar producers (including hall-of-famers Mannie Fresh and Organized Noize and mere all-stars DJ Khalil and WLPWR) and an MC guest list to match (T.I., Bun B and the late Pimp C, CeeLo Green, Jill Scott, Bilal and Robert Glasper Jr.). He helms half the mammoth album himself, and his syrupy flow — a spiritual descendant of Houston (Geto Boys and UGK), Atlanta (OutKast and Goodie Mob) and, first and foremost, Meridian, Mississippi — is all over it, first in Clipse-eclipsing braggadocio on disc one ("Your confetti ain't even heavy," he rains over a vampiric video-game sample), then in a mirror staring match on disc two ("Mixed Messages" dares to taunt an on-the-nose bullseye). This "Heavy Is the Crown" tour smudges the fine line in between, a weigh station for the conscience behind the concussions. chyitheprynce, Childish Major and DJ Raj Smoove open. Tickets $25-$65. At 8 p.m. Wednesday. House of Blues, 225 Decatur St., (504) 310-4999; www.houseofblues.com/neworleans.
