When To Pimp A Butterfly came out, it seemed like Kendrick Lamar forgot one song. The series finale of the Colbert Report had K.Dot performing an untitled track that appeared to be intended for his album.
TPAB producer Terrace Martin has revealed that the song was was written specifically for the performance and there's not even a master copy of it sitting on TDE's hard drives. "It don't even exist nowhere in the world," Terrace says.
Martin also touched on the mysterious identity of producer LoveDragon, who's credited on the album. Some believe that it was Dr. Dre, whereas others have suggested it was the duo of Martin and Josef Leimberg. Martin, while not revealing who it is, did confirm that it's not an alias of Dr. Dre's.
