TDE’s CEO Top Dawg announced that earlier this week he would be dropping a new project from one of the label’s artists sometime this week. Fans expected a project from Isaiah Rashad, SZA or Ab-soul but were pleasantly surprised to find out that the new project was from none other than rap god Kendrick Lamar.

According to the rapper, untitled unmastered. features music made between 2013 and 2014 while creating his last album, To Pimp a Butterfly, and should be considered a project rather than an official album.

“I got a chamber of material from the album that I was in love where sample clearances or something as simple as a deadline kept it off the album, But I think probably close to ten songs that I’m in love with that I’ll still play and still perform that didn’t make the cut.”
