This prompt is well posed and something I've thought about a fair bit as well. So much of it comes down to presentation, context, editing, etc. If a sound is recorded or processed in an interesting way and feels exploratory but disciplined somehow, it could easily be presented as something closer to sound art than jamming, though it may have arisen from the latter. This certainly comes through what I've heard of your music. The presentation in artwork and sound doesn't feel dashed off or aimless, so I read your music as being closer to studied exploration/composition/improvisation off a closed system - i.e. academic. That said, for all I know you sat down at your computer or equipment and recorded two 15 minute chunks of music with no pre-planning or intention between bowl hits to blow off some steam after work.
All of this brings to mind that fantastic Edition Omega Point imprint - Obscure Tape Music of Japan. By and large the music is academic or sound art, but long portions of the first two tracks on the Toshi Ichiyanagi - Music For Tinguely release wouldn't sound out of place on many a primitive, raw, spur of the moment noise release. Meanwhile the flatlined drum machine sound of "Environmental Mechanical Orchestra" on Tape Works Of Kuniharu Akiyama 1 aligns with many of the most dystopian and raw characteristics of certain early-80s industrial noise or even certain Baltimore/Providence circuit-bent/cracked electronics music (like that guy Door's projects Copper Glove or Dust.) On one end of things we have a person, "known for his studies of Erik Satie and Japanese film music," who was married Aki Takahashi, in the middle a shadowy, extremely prolific and creative period of underground music, the original releases of which sell online for hundreds of dollars, and then on the other end music which is slotted in my mind, perhaps unfairly, alongside a crusty jammy hipster aesthetic of Mickey Mouse swastikas, MySpace, Class of Nuke'Em High, etc. A blind taste test would likely be a different experience.
I agree with what you're saying about documentaries on noise projects - I enjoy reading oral history but in general I'd prefer not to watch a documentary on an artist whose work I connect with. I feel the same too about live footage much of the time, Incapacitants are a great example. I'd love to see them live someday and something like the Kingdom of Noise video is definitely enjoyable, but watching a 4k/binaural live recording on YouTube leaves me feeling kindof depressed and is something I avoid. I'd rather close my eyes and listen to a cd and leave it at that.
Concept, context, or presentation are what pique my interest much of the time, and a certain amount of open-endedness. The less, the better, generally. Thanks again for this prompt, I hope more people reply.
