The stretch involves a rolling, ornamented retro-contemporary production from Adrian Younge and Ali Shaheed Muhammad (with vocal assists from Bilal and Cee Lo Green), a stitched suite that is alternately stern and humorously off the cuff (featuring Egypt, five-year-old son of Alicia Keys and Swizz Beatz, as co-producer and vocalist), and a finale of Thundercat-propelled funk.

Remarkably, this hits its stride in the second half. offers this and other variations on the connected themes of societal ills, faith, and survival that drove the output it follows, with Lamar at his best when countering proudly materialistic boasts with ever-striking acknowledgments of the odds perilously weighted against his people. He observes terrifying scenes all the while sensing possible relief ('No more running from world wars,' 'No more discriminating the poor'). After an intimate spoken intro from Bilal, the set segues into an urgent judgment-day scenario with squealing strings and a resounding bassline as Lamar confronts mortality and extinction with urgent exasperation. Track-to-track flow, however, is about the only aspect of this release that can be called smooth. This was assembled with a high level of care that is immediately evident, its components sequenced to foster an easy listen. The dates indicate that the majority of the material was made during the sessions for that album, and the presence of many of its players and vocalists is unmistakable. A postscript, it's (artfully) artless in presentation - not even basic credits appear on the Army green liner card in the compact disc edition - yet it's almost as lyrically and musically rich as To Pimp a Butterfly.

Apart from segments previewed at the Grammys and late-night television appearances, there was no formal promotion.
