Here's Kendrick Lamar performing "Poetic Justice" live on Late Show with David Letterman . Don't know how to break the news to you guys, but Drake did not join him. BUT, Kendrick's band's saxophone player did. In fact, this might be the saxiest rap performance in recorded history. Also, worth watching to see Dave awkwardly shout out Compton at the end.
