Off first listen.
I will say I like it. It's quite different than GKMC and TPAB. In a sense, this is likely Kendrick's Graduation. This album will fare very well with casual crowds, and I think this will make Kendrick a mega superstar. It will sell a lot. If Humble's success is any indication, the singles will do just as well.
Thematically, it's hard to pin point a specific story or trope riding throughout. It's more varied than his previous offerings. Lyrically, I don't have a clue what each song means. I usually digest Kendrick's lyrics on the third or fourth listen, typically because they're a bit more dense than other rappers and the overall message is sometimes buried.
Sonically, though, it's incredible. Hard to say it's better produced than TPAB, which was simply incredible with all the live instrumentation and different hands in it. Sounds like a more mature GKMC/Section.80 in terms of production. Kendrick ditched the pitched vocals for the most part, which was something I had hoped he would do. Just straight bars for the most part.
