I love collages. I love the energy and narrative that results from "random" things coming together. As if it's actually random. Which it isn't, of course. It's totally considered and curated by the artist. Someone thoughtfully orchestrates the apparent disorder. This art form for some reason, totally moves me.
And speaking of collages, I really like the work of fred free, which I found on the terrific collage blog collage mania. Each piece stands on its own individually, but he also creates boxes and "books" that need to be seen collectively. The narrative of the one collage becomes one chapter of the narrative of the entire collection. Very cool.
