you said he had one of the best albums in years and now you asking what he changed?
I think a "lane" is a definitive style that an artist works on and improves over time, and Kendrick's "lane" is great story telling. I can't think of a good way to describe his sound but he definitely has one.
but honestly I guess there aren't too many people jocking his style because it's not as pedestrian and easy to copy as Wiz's, so I don't know how you say Wiz's style is so original. . . Devin The Dude & Bone come to mind.
but Kendrick stay getting acclaim and brought up in "bringing the west back, keeping it alive" talks, not to mention his album that just dropped so it might take a lil longer than two months to figure out just how big of an impact he's making.
