This thread is for sharing rare demos, remakes, and remixes. (and it has to come from third party uploader)
my findings:
Demo
unwish (girugamesh’s period demo)
it was originally available on Ryo’s Channel but he private the video (possibly for personal reasons)
Remake
Girugamesh’s Goku (2011)
Haven’t found any remixes yet
GOKU re-recording was officially included in NOW super limited edition, their album in 2009, as a bonus track along with 獄窓(NOW).
is the limited edition itself still on sale? because stupidly chose to go with streaming instead of physical.
No physical copies anymore unless it’s second-hand.
Girugamesh also has several remixes by TeddyLoid which weren’t released officially.
