I’m on the opposite side of the coin. Being from an Brazilian family with italian ascendence, i live in a really hot family, or so to say. We’re all about hugging and kissing, and i gotta say that we found pretty strange the distance between people you find there in Europe and North America.
What is more strange is that… Well, being close, touching the people you like and love is good, it feels good to have the body warm of an important person, or even a not so important one, and, hell, i cant see not even one thing bad from it, so, why the hell you guys avoid it so much ?
And, not considering myself an artist, i can imagine how this would reflect in art. Its cultural, its a cultural diference between europeans and latins, and, as others cultural diferences, it should affect art. But, not being an expert, i will not dare to say how.
But, nodaways, i imagine that it would affect art in two diferents possibilities :
a. The lack of human touch would make an artist reflect his needs for human contact in art, creating strong coloured and sentimentally heavy art, or;
b. The artist would reflect his distance from people in art, making cold, brutal and/or desperating pieces.
But, of course, we cannot simple generalize it, since artists are a crazy species, and we can find any tipe of art coming from anywhere, but i do believe that this lack of human contact would affect art.
Just my 2 cents
