It's impressive how quicklyKendrick Lamarhas gone from being a newcomer to one who can help other new kids build their careers (also: Hood By Air! That's a look). K-Dot was performing a concert at New York's Galapagos Art Space for Footaction yesterday when he brought out UK singer Emeli Sandéfor the profane masterpiece "B**ch, Don't Kill My Vibe."

The two previously worked together on her overly catchy single, "Next To Me." Check out the live footage below.
