“I got power, poison, pain and joy inside my DNA / I got hustle though, ambition, flow, inside my DNA.” In “DNA,” Compton rapper Kendrick Lamar establishes the central thematic through line of his new album, or, more accurately, confesses that no such single through line actually exists. Damn lacks the driving narrative force of Good Kid, M.A.A.D City and the political consequence of To Pimp a Butterfly, but that doesn’t mean it lacks purpose or emotional potency. Lamar has a lot to say, and unlike his past two studio albums, he doesn’t use a storytelling device to say it. After two critically-acclaimed concept albums, it may be tough to swallow Lamar’s return to a more standard album format (i.e. 2011’s Section.80), as it was initially for me. However, Lamar remains as deceptively dense as ever in how he balances vocal delivery and lyrical content, crafting songs that are as poetically meaningful as they are sonically enjoyable.
