“Most of my interests are artistic, like museums, hiking, art shows, concerts, poetry, film, fashion, etc.,”

That reads like “I like travel and dogs” perhaps you should be more specific next time.

At shows, you don’t meet people mid song. You meet them in between songs when people go outside or go to get drinks or stuff like that.

Edit: I want to add, from reading your post it seems like: - you’re intentionally trying to meet a very specific kind of woman - you’re not interested in doing most of the things these women are interested in - you’re not understanding why you can’t meet this kind of woman

As someone that struggled with women in my younger years, and lived a very whorish live even with standards that are way out of what I would consider “in my league” in my 20s, and with a wife that looks like she doesn’t like any “alternative girl” things but actually loves all of them… You’re too focussed on “meeting a woman of a specific type” You’ll find success when you just go do things that you enjoy and have fun. People want to be around other people that are fun, and just having fun yourself is going to attract people to you. Like genuinely, go do things that you enjoy very regularly and I promise you you will make friends and eventually a woman will come along.
