Following teases from Black and Gass regarding a second film, in late 2018, the band began independently releasing an animatic hand-drawn web series titled, Tenacious D in Post-Apocalypto, each of the six episodes uploading exclusively to YouTube every week starting September 28. Columbia Records released the album Post-Apocalypto on November 2, 2018, just after the release of the sixth episode.

It took a few years after meeting in the early 1990s for the two to begin writing music of their own. Black and Gass eventually wrote their first song after Black had been dumped by a girlfriend called Melissa, a non-comedic song. The two have since admitted to feeling embarrassed about the song, though they
