Though fans that complain about rap deviating from its roots often come across as old curmudgeons, those contemporary emcees who practice vintage rap don’t seem to ever go out of style. Take BK rapper Latasha Alcindor (aka LA)’s latest track, "Revoke Thee," for example. Over a jazzy instrumental with attitude, LA delivers hard-hitting lyrics in varied flows that could very well have been blasted out of the boomboxes of yesterday. Like her ballsy predecessors Lauryn Hill and Queen Latifah, she also exudes a great deal of swagger in her lyrics. With "Revoke Thee," and its accompanying video (streaming below), LA has proven she is an emcee to watch, and a crucial one at that. She has a an LP due out in February. – Henry Solotaroff-Webber
