Collaborator Sounwave said: "We have a lot of [other] records, especially from this album.

"There are still records people haven’t heard, mainly because we can’t get sample clearances.

"Those songs were ones that we really loved and were hurt that we couldn’t put them on the album."

Lamar has had an impressive year so far winning a staggering six Grammy awards and reaching the top spot for his latest album despite only alerting fans of its existence by tweeting a link to iTunes.
