Take the feeling of knowing your mother has just found a four-page account of your first acid trip, or worse still, a Polaroid of you in a compromising pose, and magnify your audience to include the entire nation. I suspect some people have experienced that horror, all because of one man’s art project. And yet it’s impossible to look away from the cultural car wreck that is FOUND Magazine, author (and This American Life contributor) Davy Rothbart’s zine dedicated to the detritus of all of our lives. It’s simple: people find amusing notes or pictures on the street and send them in, after which they’re collaged into a themed artwork by Rothbart and his friends. Raunchier submissions end up in Dirty Found, although the guilty do get black bars over their eyes (but nothing else). To celebrate the release of FOUND #5 (The Crime Issue), Rothbart shares his favorite finds from the issue while his brother, musician Peter Rothbart, plays songs based on them. Laugh all you want, but keep your fingers crossed. You never know what you may have dropped.
