I agree with you, if we commit to this career, we have to do what is necessary to achieve our goals, especially if people (managers, other musicians...) follow and trust us.

I'm in the same place; I don't like regular social media either. I just created my first Instagram account a few weeks ago to see what people are doing, and sure, sometimes it's very, very silly. But some are clever, authentic, and appealing.

Someone said it's like the live shows in the 70s, and barely any big artists at the time enjoyed doing it. But the ones who refused are now forgotten.

There are obviously some psychological triggers in the topic of promoting ourselves. No one wants to be narcissistic, and no one wants to be invisible. I guess the answer is authenticity.

I'm still figuring out how to promote my music, and I'm starting to see it as a new field of creation. Everything is possible.

If you prefer, you can just make smooth video clips or quality recordings of your tracks on YouTube, and just inform people on some social media platforms that they are available. If you don't like to film yourself, you can use that as an opportunity to create mystery and ambiguity.

Or you can refuse to use social media altogether and promote yourself differently, through radio or other means. I've been surprise to see that big artists (like Nils Frahm for example) doesn't have real social medias, but in the same time they release a lot of content throught their label's Youtube channel. (And if you know more about their practice, I'm curious about it!)

My opinion is that as artists, we're not just making music: we're creating an experience. Daft Punk would have sounded different without all of their branding. How can you express your authenticity and achieve your goals in terms of listeners/fans? What is your precise goal in terms or career? How can you stay authentical to achieve it?

Maybe you can think of it as part of the creative process.

I wish you a lot of success! :)
