Vibe and McDonalds recently teamed up for the Big Mix producer challenge, which was a search for the best up-and-coming producers out. Big K.R.I.T. served as the guest judge for the competition and selected Flint, Michigan duo Foreign Allegiance as the winners. As part of their prize, they got to collaborate with Krizzle on a track. You can listen to the end result, "What You Know About It," below. You can also check a video of their in-studio session, below.
