With his latest album, Underground Luxury, B.o.B. promised a return to his snarling Southern rap roots. Hell, he even went as far as telling BET the new record will be the “Album of the year. Hands down.” For a third time, the latte-slinging, party-throwing minds at Whynatte are bringing the Grammy-winning artist to Smith’s Olde Bar on Christmas Eve. Before he took “Airplanes” to travel through “Strange Clouds,” B.o.B.’s hometown shows with Whynatte bordered on legendary. For an artist looking to reclaim his lyrical gusto and a fan base just as eager to hear it, there is no place like home.
