Many years ago I was in Madrid for a time. One of my flatmates was working at Reina Sofia museum and she offered to tour me around. There were many famous paintings in there (Picasso, Dali...), but at one point she said she was going to show me one of the most treasured paintings in the museum. At guess what, it was a painting of one of those queens/duchesses (of the 17/18 centuries or something like that I guess, can't remember who it was depicted or who the painter was), you know, the plump ladies with red cheeks and colorful dresses. And I was like, what, it's ok, but nothing special. Then she start explaining the technique (probably groundbreaking at the time it was painted), how the colors blended together and all that, and it was like a revelation to me, I start paying attention to all that and it was a god damn nice painting, more than nice, it was great.
And this happens to me now and then, with movies, music and all forms of art. Through others, reading, just growing up, perception of things change and what once had seen common becomes beautiful, and the other way around. That said, there are many pieces of art and artists out there that I have tried to feel, but just can't do it no matter what (not referring to Messiaen). And that is just fine with me, I just don't bother.
