Now that the disappointment that was the Grammy Awards are over, we can reflect more upon the events that made this year's Grammy weekend in LA great. In addition to many fantastic parties, we also caught wind of some performances, Janelle Monáe's notwithstanding, that made not watching the Grammys that much better. To the surprise of many in the crowd at the Mos Def show at the House of Blues came a reunion of last decade's dopest Hip Hop duos, Black Star. Not ones to disappoint, Talib Kweli and Mos kept it real by performing their classics "Definition" and "Respiration." Relive the awesomeness below.  Much thanks to Tunji for this.
