Perhaps the best brothers working outta Europe at the moment, Les Freres Chapuisat aka Mentary brothers, are doing another of their jawdropping installations, this time in Paris, so if your in the area and not rioting at Gare Du Nord, go see this show...you will never forget them. The other artsists involved look equally awesome too.
Below is a flyer and then a photo from a previous piece of theirs. They are kings of interaction in installation pieces, making you explore their work rather than just observe. Previous work has included making GIANT ants nests in gallerys out of cardboard that you have to crawl around to negotiate. They basically rule, gregory is a ladys man and they not only kill installations but their drawing skills are too much as well...you gotta check them out!
