Big K.R.I.T., a Mississippi rapper born Justin Scott, is one of the latest in a crop of hailed would-be saviors of rap with the power to satisfy both casual fans, Internet rap nerds and picky critics. But the twist with K.R.I.T. is that — unlike other twentysomethings in the same position — his sound is unabashedly Southern and hip-hop, skipping the kind of electro-pop production currently in vogue for "urban" radio formats. On last year's lauded free mixtape Return of 4Eva, he married both straight-ahead boom-bap beats to jazzy licks, swampy soul and an undisguised drawl. Lyrically, K.R.I.T. never shies away from biting commentary, especially about his industry peers (just note the initials and substance of Return's track "Another Naive Individual Glorifying Greed and Encouraging Racism.") This performance should also include a few selections from 2011's Last King 2: God's Machine.
