As rumored, Kendrick Lamar appears to have new music on the way, and on Friday morning he dropped a minute-long teaser titled “GNX” that is supposedly part of a larger work.

The song has a siren-like drone in the background, while many multi-tracked Lamar vocals create a complex, chant-like melody that is more similar in feel to many of the songs from his most recent album, ‘Mr. Morale and the High Steppers” than his blockbuster Drake-dissing track “Not Like Us,” which was released earlier this year and topped the Billboard Hot 100. The lyrics are difficult to understand, but we are sure they will be posted on Genius. .com soon enough.

Although Lamar’s music is usually released slowly and deliberately, he has released four singles this year — “6:16 in LA,” “Euphoria,” “Meet the Grahams” and “Not Like Us” — centered around an unusually aggressive feud with Drake, after the text of the Canadian rapper who characterized himself, Lamar and J. Cole as equals. The comment seemed to speak to Lamar in a way he hadn’t previously in his career, starting with his guest verse with Future and Metro Boomin on “Like That,” which was also a big hit single this year.

He’s worked with a number of different producers on those songs, including his longtime collaborator Sounwave and Jack Antonoff, the Alchemist, Sean Momberger and others.

He also headlined a Los Angeles concert called “Ken & Friends” in June, where he was joined on stage by his early mentor, Dr. Dre. The show was divided into three sections, the first a set of West Coast artists led by DJ Hed, the second led by “Not Like Us” producer Mustard, and the third headlined by Lamar.
