Kendrick Lamar is constantly praised for his lyrical ability, his narrative, and his concepts, but his vocal approach isn't talked about nearly enough. Listening to To Pimp A Butterfly, Lamar manipulates his delivery constantly, from ferocious nearly-yelled raps, to bizzaro alien flows, to exasperated whines. The last of those styles was mastered on "The Heart Pt. 2," which found the rapper experimenting with breath in a way we hadn't really heard before, leaving all of his gasps in place as he rids the rhymes from his body like demons that he could no longer contain.
This was before good kid m.A.A.d, city, even before Section.80, but it was still clear Kendrick had something special to offer.
Occupying my time with riches,
Justifying my time and ambitions
Just to coincide, just to go inside,
Plus we idolize why we living
Look the mastermind, took the masters mind
Just the perfect time, just to master mine
Just to match the grind with precision
