Rick Ross has had some very interesting collaborators as of late. The rapper, whose message is typically dominated with messages of street hustling and a life of luxury, has recently appeared on records with Lupe Fiasco and Big K.R.I.T. Now, Killer Mike, one of the Hip-Hop’s most outspoken activists (in his music and otherwise), joins Ross on the remix to Black & White, along with Stalley and Gunplay. Further, Ross changes the chorus and his verse to speak directly to the killing of Michael Brown and the recent turmoil in Ferguson. Check it out.
