It’s unconfirmed, but believed, that Demolicious was actually recorded after the release of the trilogy. Billie Joe was quoted in 2016 by Rolling Stone saying “The intention was to make (Uno, Dos, Tre) more raw and off the cuff and the opposite happened”.
The record store day release called “Demolicious”, to imply they were early versions of the songs, is probably more of a second take at them in the way Billie originally intended.
