If you've never hit up Walter De Maria's New York Earth Room, I suggest you pay this permanent installation a visit. Absorbing the notion that a 3600 sq ft NYC apartment (within the boundaries of Soho's most precious real estate radius, no less) is filled with 2 feet of dirt boggles the mind. It also fills you with a desire to cast your shoes aside and frolic past the observation barrier to feel the soil squish between your toes.
One group of kids documented a mud wrestling fest in the Earth Room (click here to download the video, .mov file), clocking in just under a minute's worth of forbidden glory (you'll find photos of the 2003 Brooklyn Condiment War if you delve further into their site, just beware of the hippie nudity).
De Maria was an experimental recording artist, and self-released an album called Drums and Nature in 1968; click the song titles below to hear them in real audio.
