As if today needed a reason to get any better. I'm glad Yasiin Bey has found spiritual enlightenment and that his career as an actor has been gaining traction, but, that said, I miss Mos Def. I'm still kicking myself for not catching the Black Star reunion at Bonnaroo a couple years ago (cause they were playing a late night set and I was beat by that point). And, ladies and gentleman, Mos Def is back! He just dropped a new Ski Beatz produced joint, "Sensei on the Block," and this is the old-school, "Mathematics" Mos Def that we fell in love with back in the day. Here's hoping this leads to a new album this year.
