Chicago's 4th annual Versionfest is 18 days of experimental art, guerrilla graphics, indie music, political activism, and technology, opening today, 20 April 2006, and running through 7 May 2006. For the Urban Gardening and Exterior Decorating Show, artists painted and appropriated neglected spaces around the city into "charged public spaces." Opening night features a ‘kunsthalle’ and on Thursday 27 April, 2006, the festival hosts an exhibition of music and sound art called the International Noise Awards. Ed Marszewski, or Edmar as he's known, is the founder and present curator of Version and the alt-culture mayor of Chicago. Edmar has been facilitating culture-changing collaborations since the early 1990’s. He gave first exposure to Bobby Conn and the Aluminum Group was formed to play at parties for his short-lived magazine Easylistener.
