Production took place over a year in Los Angeles. The bulk of the project was shot during two and a half months, capturing pre-production through the entire production schedule. The documentary's narrative is driven by an intimate interview with Rob Zombie, shot several months later over three days at Rob's home. This was the first time in his ten-year filmmaking career that Rob Zombie let someone else direct and edit the making of a documentary for one of his films, a job he had done up to this point.

After 31 premiered at Sundance in 2016, Lionsgate acquired the film for global distribution. That summer, Rob Zombie went on tour with his band. Josh and Lindsey went on the road with them for several dates, where they conducted and filmed several additional interviews and promotional spots with Rob Zombie for all of 31's VOD and physical releases.

In October 2016, 31 received a special theatrical release by Fathom Events. Relavox was again enlisted to produce a special 30-minute edit of the documentary, screened alongside 31 in theaters worldwide.

Two months later, Lionsgate released the feature-length documentary on a standalone disc with the Bluray release of 31. Additionally, Lionsgate released an extended 5-hour-long version of the documentary on iTunes in the U.S., released in theaters nationwide alongside 31 before it was made available as a second disc with the Lionsgate release of "31" on Bluray and DVD in stores worldwide. Critics praised the documentary as a standalone feature film, including Forbes, who specifically acknowledged the rare interview given by Rob Zombie.

This is the first project Lindsey and Michael joined Josh on, setting in motion what was soon to become Relavox.
