A few months ago, I went to see an exhibit at the Hirshhorn Museum in Washington, D.C. called "Visual Music: Synaesthesia in Art and Music Since 1900." It was one of those exhibits you don't see often enough--brimming with a lot of great and relatively unknown stuff, linked together in non-obvious, revelatory ways. A great museum show is like a great DJ set. It has massive build-ups and peaks. It's euphoric and surprising in places. Each piece of art leads up to something bigger than itself. And best of all, the show draws instant connections between genres, periods, styles, and ideas that you would have never guessed yourself. (If it makes you want to dance, that's cool too.) Anyway, I took copious notes, attempted to take photos (until I was busted by a guard), blew fifty American bucks on the exhibit catalog, the whole deal.
Christoph Cox wrote a good article in the October issue of Artforum on synaesthesia. I've been meaning to write an article on the topic too, but more on the science tip.
