Joey Bada$$ may be the most well known member of the emerging Pro.Era crew out of Brooklyn, but CJ Fly and Capital STEEZ, who both have appeared in video releases with Joey in 2012 (Capital STEEZ is featured on "Survival Tactics" and CJ Fly on "Hardknock"), have serious mic skills and flavor to share with the world, too.

Check out their new collabo "The Beat Grinder," where the two spit bars over a Madlib beat and show that Joey isn't the only one in Pro.Era to beware of. CJ Fly addresses being overlooked in the past on the song, rapping, "Left my name out but I don't let the bloggers get to me/As long as I still see my face on MTV." Recognize.
