Planet B features Justin Pearson (the Locust, Head Wound City, etc.) with frequent collaborator Gabe Serbian (the Locust, Head Wound City, Dead Cross, Zu) and Luke Henshaw (Sonido de la Frontera, First Power Crew). Their debut 7-inch, tracked at Penguin Studio in San Diego, features “Wrong Utopia” b/w “Join a Cult.” Released via Three One G Records, a video was shot for “Join a Cult.”

Their song “Attractive Mammals” was featured in Asia Argento's film Incompresa, and another song from the soundtrack was remixed and released on a limited edition split 7-inch single collaboration with the Invisible Scratch Pickles.

In 2017, Planet B collaborated with San Diego writer and performer Adam Gnade for Life Is the Meat Grinder That Sucks In All Things, a new prequel to Gnade's Locust House featuring minimalist jazz percussion and landscapes of sweeping, windy Eraserhead-esque ambience.

The debut self-titled Planet B album, released in November 2018, includes collaborations with Martin Atkins (Ministry, PIL, etc.), Brian Evans (Retox), Nick Zinner (Yeah Yeah Yeahs), and Sonny Kay (Year Future, the VSS). The video for "Disease Control" features Sonny Kay and was created by Eric Livingston. A video for "Crustfund" features Kool Keith (Ultramagnetic MCs).

Around the same time, Planet B collaborated with Bronx-based rapper Kool Keith (signed to Pearson's Three One G Records label) for a remix of Keith's “Blast” and "Uncrushable."

A music video for the track "[A] Not At All [B] Somewhat [C] Very Much," created by Displaced/Replaced and released in early 2019, captures the ominous, overtly political tension of Planet B's music, opening with a Cornel West quote and cycling through scenes of civil unrest. Another video was produced for "The Beginning is Near," created by Displaced/Replaced (who has worked on videos for other Three One G bands such as Geronimo and Deaf Club) and capturing Planet B’s penchant for pyromania, both metaphorically and literally.

A new single was released in early 2020, a cover of the M.I.A. track “Bad Girls.”
