Delving even deeper into the vein that 'M.A.A.D City' opened, this album is a genuine and vulnerable telling of one man's struggle in a violent and oppressive world. What stands out on the surface may sound like bravado and avarice, but lying just underneath that facade is fear, self-doubt, and despair. In sharing that story, Kendrick has lent his voice to the telling of many people's stories. The list of examples is nearly as long as the entire album, but I'd point to 'Institutionalized', 'These Walls', 'Alright', and 'How Much A Dollar Cost' as prime examples of what I'm talking about.
The tracks themselves are filled with the life and a diversity of numerous artists and musical elements from a wide array of genres. Check out 'For Free?' (spoken word), 'These Walls (R&B), 'u' (jazz), and 'Alright' (hip-hop) to get a sense of just how dynamic this album is. I think the statement from the Wikipedia article which says the album is, 'supremely "cinematic" production qualities but [with] "the freedom of a mixtape",' summarizes it perfectly.
The rhymes and rap techniques are simply on another level. The internet has covered this thoroughly, so check that out if you don't hear it for yourself. My absolute favorite flow is on the tail end of the track 'i' and I only wish that it could carry on, instead of being broken up by the fight in the crowd.
Please. Take the time to listen past the language and the talk about pussy and bitches! This album has so much to offer on every level, and it would be a shame to misjudge this book by it's cover.
