The new work, directed by Machel Ross, is called “Black Exhibition,” because, Harris said, it asks: “What does it mean to be a black body on exhibition?” He is categorizing the new work as a “choreopoem,” after Ntozake Shange’s seminal “For Colored Girls Who Have Considered Suicide/When the Rainbow Is Enuf,” which is now being revived at the Public Theater. Harris said that meeting Shange at a gathering had inspired him to use the dramatic form she pioneered.

Emboldened in part by the surprise album drops of pop artists like Beyoncé, he has chosen to keep his authorship a secret until now. The Bushwick Starr, which is planning to present the hourlong show from Nov. 6 to Nov. 23, has until now been promoting it as having been written by @GaryXXXFisher, a pseudonym created by Harris. (Update: The Bushwick Starr has extended the run of the show through Dec. 15.)

The show is being financially supported in part by Makeready, a film studio with which Harris has been collaborating on other projects.

Harris and the Bushwick Starr’s co-founders, Noel Allain and Sue Kessler, said they had embraced the idea of pseudonymous authorship in the hope that new audiences would have a chance to get tickets before they were snapped up. The space is small — a second-floor walk-up with just 72 seats — and the initial run is just three weeks, although it could be extended.

Harris, who is 30 years old, agreed to do “Black Exhibition” at the Bushwick Starr long before he knew “Slave Play” would go to Broadway, and he said this venture has become more meaningful now. “The goal of my playwriting work was to be in these kinds of spaces — it was a no-brainer to want to do a show there, but it became even more imperative while my play was uptown, to show younger theatermakers that commercial theater doesn’t necessarily have to be the goal.”
