If anyone asked me what I would like to see in the vk scene in 2020, I'd say: "the gazette traces vol 3" with more re recorded tracks. (But the old school ones,of course)
I'd like to see them go as far back as their first 3 singles. Wife and Akai One Piece sound like they would turn out well reworked and they already still play a somewhat updated version of kantou dogeza kumiai live.
