I personally really like what @tehn said in the thread @glia linked above:
the ‘various names for different projects by the same person’ thing seems relatively unique to music, though I suppose so are aliases themselves. I know roughly as many visual artists as I do musicians (many are both), and my visual art friends, dancer friends, and others don’t have different names for different projects unless they’re also working with additional or different people, even though their work may span an extremely wide range of media/content/concept/etc. Albums from many musicians and bands can be tremendously different…Radiohead didn’t change their name when they stopped playing “Creep” and came out with OK Computer, but they sounded profoundly different (as a somewhat dumb example). Perhaps more relevant: Nathan Moody’s (very good) Etudes series. They all sound quite different from each other and are made with completely separate equipment, but they’re all still him.
It can also be confusing for casual listeners who might be into one’s overall approach to music to find out about various projects by the same person, even though they might be down with everything a given artist does.
One of my most talented musician friends has ~4 different solo projects (at least I think that is the latest count), and he is the only one that can keep them all straight. To everyone else they’re still him, just doing different things. My favorite of his projects is the one he just uses his name for, and I think it ends up being his best work since he is least prone to overthinking when writing/performing as such.
Lastly, time itself tends to change an artist’s voice in ways that exceed changing instrumentation or other variables, and I could imagine it being difficult or prone to overanalysis to have multiple different projects by the same individual which are already going to be constantly changing because literally everything is already constantly changing…but this change is already represented by knowing when a given album or work falls in a given artist’s discography or oeuvre.
all that said, if you want to have various names for various projects, go for it! there is nothing wrong with that and no one should be less likely to listen to and appreciate them
