Kanau・・・ (叶う・・・) has re-released a single Keshiki (景色) via digital distribution on Jan 21, 2021. This single is available at many services (e.g., Apple Music, Spotify, Youtube Music) and even Bandcamp:
This Twitter account explains the reason why they started this digital distribution:
The followings are my translations to English:
We were encouraged by the people who were still looking for the sound source because we were depressed from not living well. So we thought we could give something in return to our fans, and instead of going back to the past, we chose a format that didn't exist at the time: digital distribution.
The predecessor band has a demo tape and a demo CD-R, but the vocals are different, so this CD is the only sound source for this band by me.
Extra note by Ryu
He does own the previous releases; demo tape and CD-R (but with a different vocalist), however when the second vocalist saw that he shared this release, he didn't receive a "nice message". So for that reason he can only share this release and not the other releases too.
