By like this movie, I mean like really like this movie, not 'yuri' or 'music' related stuff.
Like from the recommendations, Koe no Katachi is like the only movie there which can be said it's like Liz to Aoi Tori. And I know they are both by the same director so it's understandable why.
Basically, I'm asking for anime (or anything) that's like this movie, like with a lot of ambient (or atmospheric) music, not much talking, and well a bit simple I suppose ? Angel's Egg fits somewhat but not really like that.
I'm really sorry if I don't seem to make any sense here...
Is it cheating to say that I don't really think any movie is like Liz and the Blue Bird?
I think, as you pointed out, a silent voice is likely the best choice and past that I'd really recommend everything else by Yamada like Tamako and K-on.
These are more long shots but if you want really delicate and "whole" stories maybe try
the yuri is not really there, but it's implied. I think this movie is so much like revue starlight in that sense
^^^ i second this
revstar is definitely a pretty comparable franchise to specifically liz (and not really to the rest of sound euph)
like liz, it is heavily about its themes and how its characters weave into them. that said revstar is even more all-in on its core relationships and i'd argue that while liz approaches yuri ideas revstar just shoots past them and transcends what love and relationships even are.
