To me classical music is one of the last spaces where these experiences are available.
Love your posts, sir.
At the risk of repeating myself, but what you are looking for can be found in rock/pop/ jazz/ blues etc as well. Unfortunately, these uncommon gems have to be searched for and discovered yourself.
Throwing you in at the deep end, but music like this https://youtu.be/Nvoyrc6L624
is, in my opinion, comparable to the best classical can offer. ( stay with it, takes around 90 seconds to get going).
You will also note that it's uncontaminated by my least favorite musical instrument, the human voice.
As for the good Mr Shostakovich, been trying me best but eventually always return to Arvo Pärt.
As sacred and spiritual as one gets in the modern classical repertoire.https://youtu.be/xhmxGk45qu4
