Intended for the original version of The Stage in 2016, "Dose" was added to the tracklisting the following year as part of the album's transformation into an evolving body of work.
"Musically, 'Dose' was supposed to be a Part 2 to 'Roman Sky' and had a very cinematic feel, but we turned it into more of a tripped-out metal song," said vocalist M. Shadows.
The lyrics tell the tale of a mysterious traveler who claimed to have journeyed from a country called Taured, in another dimension. Shadows explained the story behind the song:
"The lyrics were inspired by an unsolved mystery that dates back to the 1950s about an airline traveler who, if you believe the story, supposedly fell into our dimension from another.
According to reports, he showed up in a Tokyo airport with a passport from a country that didn't exist anywhere on a map. He was detained for questioning, but mysteriously vanished from a room guarded by immigration officials, taking with him all evidence of his existence. It ties into the theory that there are infinite possibilities of our lives being played out across space and time.
Don't know if the story is true, but I'm fascinated by that kind of stuff and thought it'd be a fun idea for a song."
The song soundtracks a level for Dungeon Hunter 5. The mobile game features a special level inspired by the artwork from The Stage.
