KENDRICK LAMAR 'Untitled Unmastered.'

KENDRICK LAMAR has released a surprise eight-track album, 'Untitled Unmastered.', comprising outtakes from the Grammy-winning 'To Pimp A Butterfly'. Filled with jazz solos and politically-charged lyrics, it appears to be a companion piece 'To Pimp A Butterfly', rather than a standalone record. All of the tracks are untitled, save for the date they were recorded.
