Fifty years ago, Nam June Paik scattered television sets around the Galerie Parnass in Wuppertal, Germany, and proceeded to use magnets to distort the pictures on their screens. Today we look back at Paik’s Exposition of Music-Electronic Television as the moment when video art began. To celebrate the medium’s half-century mark, the Magmart International Videoart Festival has organized 100x100=900, an exhibition featuring 100 video artists, each contributing a piece representing one year from the past century. The artists are pulled from former festival winners and represent five different continents. This international show is currently on an international tour and — of course — this train will be stopping in Nashville. During July, Seed Space will be screening all 100 videos, dividing them into weekly sets of 25. At the beginning of August they’ll run the whole series again. This gives gallerygoers plenty of opportunity to make the trek to the Wedgewood-Houston neighborhood and take in a wide-ranging survey of contemporary video from, well, everywhere. I’m reminded of the successive weekends I spent at The Belcourt watching all 15 installments of The Story of Film. If these works are half as illuminating about the state of contemporary video as Story was about the developmental leaps that created modern cinema, it’ll be worth the return trips.
