As part of his cover story with Mass Appeal, Kendrick Lamar revealed a fun little tidbit — more to the album title on the inside of the booklet to To Pimp A Butterfly.
“[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,” Kendrick said. “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.”
Alison Hawes, MS—a teacher of the visually impaired (TVI)— said to Complex that Kendrick used uncontracted Braille, the most basic form of the writing system, in his message. The direct translation is ”A Kendrick By Letter Blank Lamar.” If you rearrange the subtitle, it can be read: A Blank Letter by Kendrick Lamar.
This is now 2 for 2 for Kendrick as the subtitle for his first album was: good kid, m.A.A.d city: Short Film by Kendrick Lamar.
Pretty interesting and among the interesting read over at Mass Appeal here.
