The duo are recording a rock version of Britney Spears’ hit song …Baby One More Time for Kung Fu Panda 4. 

Just last year, Black revealed that of all his film and TV credits, he’s most proud of his work with Gass.

‘In a weird way, it might be Tenacious D In The Pick Of Destiny because that’s the only movie that I wrote,’ he told People of his 2006 music comedy film. ‘So, that one is actually my real baby. Maybe it’s not the best, but it is my proudest.’

Kyle’s trademark role came in the HBO series Tenacious D (1997-2000) that features the fictional accounts of the real-life duo of the same name, which comprised Kyle and Jack, who he met in the 1990s after he joined Tim Robbins’ The Actors’ Gang in the early 80s.

Since the start the guys have been all about the heavy rock ‘n’ roll power chords and lyrics that talk about sex, Satan, and why they are ‘the greatest band on Earth.’ 

Episodes are typically bookended by scenes of the band performing at an open mic night, with the events in between often serving as inspiration for a song performed at the end.

According to Kyle, HBO offered Tenacious D a deal to make ten episodes, but in doing so, they would have to relinquish their role as executive producers.

Ultimately, Kyle and Jack decided to make a movie instead of giving HBO creative control of Tenacious D, and they made Tenacious D In The Pick Of Destiny (2006).

Set to the group’s song To Be The Best, the images include two full-body looks of Gass, before and after.

On the left, the rocker looks straight at the camera as he poses shirtless with his hands against his body, while the one on the right shows Kyle flexing his arms, all while flaunting his slimmer physique. 

The Walnut Creek, California native added the hashtags, ‘#progressnotperfection #nothingtastesasgoodasthinfeels #dzercise,’ to the caption.
