Most of the time, a hip-hop record quick to indict the influence of pop culture and the moral fiber of our youth is simply a front for its creator’s encroaching obsolescence. Not so with young Compton native Kendrick Lamar’s galvanizing Section.80, which plays out more like a manifesto than a sermon, stoked by the credibility and understanding of someone trying to guide and understand their peers rather than bring down judgment. You like knucklehead gangsta shit with third eye-blinding abstraction? Empathy for women’s struggles followed by a track called “The Spiteful Chant” which says “suck my dick” about 375 times? Lamar’s got your back: Section.80 is a complicated record because life is complicated, but then again, you could just knock “Rigor Mortis” and just enjoy a phenomenal talent simply rapping his ass off.
