Name-dropping Southern hip-hop has become something of a hipster commodity on a national level in recent years, but nobody covers the music and the scene as thoroughly as Atlanta's own Maurice Garland. With his self-titled blog, Garland is not only the undisputed authority on rap south of the Mason-Dixon, his well-curated mix of new music, interviews, commentary, and music criticism has elevated him a level above tastemaker to cultural guardian. When Killer Mike decided to title his new album R.A.P. Music, it was in reaction to Garland Tweeting his thoughts about the state of "Rebellious African People's" music.
