On my Spotify artist page, I have a total of one (1) release of my own - Aquanaut. (Serial Human is managed by M3rck)
I've uploaded Aquanaut to Spotify as more of an experiment. It's a loudness remaster, missing an important bit of the original release. Nominally I plan for no Esem release to be available on Spotify for five years after I've released it on Bandcamp. This would make Scateren available in 2021, and | | in 2022.
The online music scene, namely Bandcamp and Spotify of it, are a black hole of a topic. Somehow it doesn't feel appropriate to share my not-very-distilled thoughts yet.
