Mos Def (or Yasiin Bey) has been a lot of noise lately. After dropping a stellar cut in "Basquiat Ghostwriter," Bey returns with "Sensei on the Block." "Sensei on the Block" is produced by Ski Beatz and features Bey going in with serious rhymes. This is truly a track meant for his day one fans, and it's a pleasant surprise! Check out Mos Def's (Yasiin Bey's) new track "Sensei on the Block" after the jump.
