During his Amphitheater performance Wednesday night, Kendrick Lamar noted the last time he was here, "the energy was so motherf*ckin' loud," and if that was a 10, he wanted this show to hit a 12. Well, it certainly felt like a 12, with the packed crowd bobbing their heads, swaying their arms and just generally going crazy for every verse. And even though it barely lasted 60 minutes, Lamar's vigorous fireball of a set gave them plenty to go crazy about.
