Last year, the London producer Bok Bok worked on “Guns & Synths,” the opening track from the L.A. future-soul singer Kelela’s wonderful Cut 4 Me mixtape. Last week, Kelela returned the favor, singing on Bok Bok’s new glitch&B single “Melba’s Call.” Kelela is also in the song’s brand-new video, beaming her image into a futuristic recording studio that’s otherwise cold and deserted. Watch the video below.

The “Melba’s Call” single is out 3/31 on Night Slugs.
