In a recent interview with Mass Appeal, Kendrick Lamar revealed that his already fraught-with-meaning album title To Pimp A Butterfly has yet another layer. In the physical booklet for the CD there is some braille that includes an additional part of the album title. Here’s the artwork in question:

Kendrick explained:

[There]’s actually a sketch of braille that’s added to the title hidden inside the [CD] booklet that I don’t think nobody has caught yet. You can actually feel the bump lines. But if you can see it, which is the irony of it, you can break down the actual full title of the album.

Complex reached out to a teacher of the visually impaired, who said the braille translates to “A Kendrick By Letter Blank Lamar.” A further puzzle or an error in braille syntax? Either way, the phrase obviously should come out to “A Blank Letter By Kendrick Lamar,” mimicking the way Good Kid, m.A.A.d City’s title was appended with “A Short Film By Kendrick Lamar.”

Rihanna also used braille on the artwork for both “FourFiveSeconds” and “Bitch Better Have My Money” — between her and Kendrick I’m guessing this will become a trend.
