Here's a few video clips from Kanye's Summer Jam performance this past weekend. Above is his performance of the "Lollipop Remix" alongside Lil' Wayne and below is his crazy impromptu acapella freestyle after fuckin' up the lyrics to "Flashing Lights" that really god the crowd going. 'Ye has really become quite the emcee as his career has progressed. I was just listening to his whole discography the other day...and his lyricism + rhyme patterns have become so much more developed, you can tell that he really works on his craft and takes great care penning his lyrics between projects.
