Throughout the years I came across various works that either belongs to the Lowercase genre or the Mircosound genre. The later I think is also called Glitch. It was in the early days of Internet music services, like Napster and Soulseek I came across this first artist and album belonging to this genre. Ryoji Ikeda and his album +/-. The super minimalistic sounds fascinated me. This was never an album that I listened to a lot, but from time to time I play it. Mostly occupied by other slightly more melodic music, I never took the time to dig into Microsound or Lowercase genres. I checked Spotify for a few artists you mentioned, and some of them have part of their work uploaded. With renewed fascination and interest, I'll for sure dive into this more.
