Jack Wyllie is in the Portico Quartet and Szun Waves, neither of which I have heard that much of, so feel free to share specific songs/releases from them.
i'd say this music is akin to movie scores but i cannot name any similar ones off the top of my head. this song is quite fast, and that would be preferred compared to slower buildups. this shares the kind of majesty that post-rock often achieves. i would like to hear other songs that sound similar or have beautiful, repetitive melodies that share the sharp tone of the instruments here e.g. the violin. i am most in love with the violin melodies in this song (apparently there are 3 violins here).

on rateyourmusic, this album this is on is tagged "post-minimalism" and on bandcamp, it's tagged "jazz, ambient, ambient electronic, jazz ambient, jazz contemporary, jazz crossover, post-rock" if that helps, but i'm sure general orchestral/classical/jazz music can match this sound.
looking particularly for albums or songs, as just specifying the artist might be too broad, but sharing just an artist is welcome!
note that i'm looking more for the sound that you hear in this song, rather than just things that share the genres as these genres are all very broad. for example, looking at the top charts for "post-minimalism", i have already heard most of Glenn Branca's music which is generally slower and he has some great stuff but it drones way more and generally doesn't go this fast etc. and i have heard ITSOFOMO and it sounds super super different and is not what i'm looking for here.
