Sounds like an interesting concept if you're down in The Cities over this coming up weekend.
Northern Spark is a new MN Festival modeled on a nuit blanche or “white night” festival—a dusk to dawn participatory art event along the Mississippi and surrounding areas. It will take place the evening of June 4 (sunset 8:55 pm) till the morning of June 5, 2011 (sunrise 5:28 am).
Northern Spark will include a diversity of art forms and projects including multi-story projections, audio environments with vistas, floating works on barges, houseboats and paddleboats, headphone concerts, and the use of everything from bioluminescent algae and sewer pipes for organs to more traditional media such as banjos and puppets [...]
It is in this context that more than 200 artists are presenting 100 installations and performances for Northern Spark from the top of the Foshay Tower to boat rides along the Mississippi to light sculptures and projections to performances galore, including car horn and brass band fanfares, color guards, river dancing, sewer pipe organs, lullabies, and storytelling. Perusing this site will introduce you to the rich variety of offerings that will bloom for one night only. It is not our goal to take over the night like some giant big top tent, but to join it. We meet the city halfway. As you walk or ride a bike or take the bus from one venue to another, see and appreciate your surroundings with new eyes and ears. Celebrate one of the great rivers of the world through two magnificent cities and enjoy the next artistic intervention you come across. It’s an adventure. You make your own journey.
