Kendrick Lamar recently opened up about a “chamber” of music he loved that didn’t make it onto his Grammy-winning 2015 album “To Pimp A Butterfly,” and now the rapper's fans can listen to those songs. During the middle of the night Friday, Lamar released a new album called “Untitled Unmastered.” The eight-track project includes untitled songs recorded in 2013, 2014 and 2016.

As previously reported, rumors Lamar was dropping a new album first surfaced Thursday morning after his record label boss Anthony “Top Dawg” Tiffith posted on Instagram that the “Alright” rapper was working on something new for 2016. Tiffith didn’t immediately clarify his cryptic post, but he later tweeted a link to Lamar’s album, writing, “Go get it.”

“Untitled Unmastered” is available on Spotify, Apple Music, iTunes and Tidal. According to Rolling Stone, Lamar has already performed a few of the new songs during appearances on “The Colbert Report,” “The Tonight Show Starring Jimmy Fallon” and at the 58th Grammy Awards Feb. 15, in which he won five awards for “To Pimp A Butterfly," including best rap album.

Following the Grammys, the 28-year-old rapper told 2 Dope Boyz there was a collection of songs that didn't make it onto his last album that he wants to perform.

“I got a chamber of material from the album that I was in love [with] where sample clearances or something as simple as a deadline kept it off the album,” Lamar explained. “But I think probably close to 10 songs that I’m in love with that I’ll still play and still perform that didn’t make the cut.”
