On Monday, Maybach Music Group founder Rick Ross celebrated his birthday, but the festivities were cut short when he was involved in a car accident and shooting. Ross escaped unharmed, but it certainly and understandably put a damper on his Born day. Today, with a little help from Kendrick Lamar’s good kid, m.A.A.d city standout, William Roberts II has a message to the shooter(s), B*tch Don’t Kill My Vibe. On this “freestyle,” Ross demonstrates his versatility, diverting away from his club-oriented style in favor of a more fluid flow that is pleasantly surprising. This freestyle freebie is merely for promo, and is not attached to anything larger, but the Carol City native did release Box Chevy last week, which serves as the lead single off his forthcoming Mastermind album.
