Kendrick Lamar's excellent 2015 LP To Pimp A Butterfly just nabbed its first Grammy of the evening for Best Rap Album. In his acceptance speech, Lamar thanked his label, Top Dawg, for taking him and other young artists from the streets of Compton to the Grammy stage. Then he said, "This is for hip hop. This is for Snoop Dogg, this is for Doggystyle. This is for Illmatic, this is for Nas. We will live forever, believe that."
