Jhené Aiko’s first album in six years, Westside Whimsy, is out now, and with it comes a new verse from Kendrick Lamar. Listen to the duo’s “So Good” below.

The track continues a partnership that began on Lamar’s 2010 mixtape Overly Dedicated, long before either artist’s mainstream breakthrough. In 2013, a year after Good Kid, M.A.A.D City., Lamar contributed a verse to “Stay Ready (What a Life)” from Aiko’s debut EP, Sail Out. Until today, that seemed to be where their paths diverged, though Playboi Carti paired verses by the two of them on “Backd00rs” from last year’s Music. Other guests on Westside Whimsy include Larry June, Ab-Soul, and, uh, Tyga.
