Jack Antonoff’s Production Is All Over Kendrick Lamar’s ‘GNX’

Frequent Taylor Swift and Lana Del Rey collaborator Jack Antonoff is all over Kendrick Lamar’s surprise new album GNX.

Antonoff, who is also the frontman of Bleachers, is credited as a producer on 11 of the album’s 12 tracks. “Peekaboo” is the only song he didn’t contribute to. The only producer to appear on the project as much is K Dot’s frequent collaborator Sounwave, who has a credit on every track. Sounwave, along with Sam Drew, is also in music group Red Hearse with Antonoff.

Outside of those two, other credited producers include “Not Like Us” producers Mustard and Sean Momberger.

This isn’t the first time Antonoff has worked with Lamar and Sounwave: He co-produced the Instagram-released Drake diss “6:16 in LA,” the second of his one-off singles taking aim at the Canadian rapper. Antonoff’s involvement with the track itself was perceived as a response to Drake’s “Taylor Made Freestyle.”

“But now we gotta wait a fuckin’ week ‘cause Taylor Swift is your new Top / And if you ’bout to drop, she gotta approve / This girl really ’bout to make you act like you not in a feud / She tailor made your schedule with Ant, you out of the loop,” Drake raps on the track.

On “Push Ups,” meanwhile, Drake credited Lamar’s success in the mainstream to his appearance on Swift’s 2015 song “Bad Blood,” his first Billboard Hot 100 No. 1 hit.

Antonoff has worked with Lorde, Sabrina Carpenter, Gracie Abrams, and The 1975 among other industry big hitters. But his closest working relationship is with Swift, with whom he has worked on each of her studio albums since 2014’s 1989.

And not that it matters, but he’s been involved with more No. 1 albums than Drake.
