From a design perspective, it's great that once in a while we see such powerful content absolutely unbranded and unnamed. What you hear is what you get. Untitled Unmastered gives you no reason to ignore it until you give it a go and hear it for the very first time. After his highly awarded and powerful To Pimp A Butterfly, Kendrick shares with the world what, apparently, was not good enough to be in TPAP. In this post I will not talk about is music, because as a big fan of his writing, anything I would write wouldn't be good enough to describe it. Now, about the album cover, it's great to see someone so humble and so successful that doesn't feel the need to hide behind appealing visuals to send his message.
In a culture where everything you share is highly curated, sometimes it's great to step back and just give room to the content.
