American singer/songwriter Patti Smith narrated an episode of Darren Aronofsky’s virtual reality experience Spheres.

The three-part series, which is directed by Eliza McNitt, made headlines earlier this year when the VR financing and distribution venture CityLights announced it would acquire Spheres in a seven-figure deal. That represented a milestone for the emerging medium, which had never sold at a major festival.

Jessica Chastain narrated the first installment, Spheres: Songs of Spacetime, which takes participants on a journey inside a black hole.

Smith lends her memorable voice to the third episode, Spheres: Pale Blue Dot,  which premieres Friday at the 2018 Tribeca Film Festival’s Immersive category.

“The big bang was silent,” Smith intones. “Then, came sound.”

This installment takes viewers on a cosmic journey told through sound, from the origins of the Universe to our Pale Blue Dot. At the edges of the observable universe, Pale Blue Dot uncovers echoes of the Big Bang. Gazing back in time, the viewer finds a path home.

Spheres was executive produced by Protozoa Pictures’ Aronofsky and Ari Handel, AtlasV, Novelab, and Crimes of Curiosity, and supported by Oculus and Intel. It is scheduled to premiere this year on Oculus Rift, then expand to other platforms.
