Insight reveals reality beyond appearances, in life and in the visual arts.
That same insight reveals false appearances as well. So it is for the composer in creating and sustaining atmospheric effects through sound. Falsified experience sounds forced, frenetic, or artificial in emotional content, tone, and mood, while genuinely immersive atmospheres evoke contemplative settings conducive to the expansion of consciousness.
Of course art is a reflection of politics. But it is only a reflection.
Culture, as a whole, presents a reflection of politics. This is visible in the degree to which freedom of expression may be pursued by artists. Otherwise, the political is of little worth when compared to the cultural.
It is only when political power usurps culture, as it has over the past decades, oppressing the arts and forcing the artist into a subservient role, that totalitarian cultures may surreptitiously rise in darkness-- but ultimately this unnatural, anti-human power can only meet a rapid and complete decline in the face of forces demanding freedom. These forces are expressions of human will that will never remain silent.
