Just finished watching the recent film made by American media manipulator, improviser, composer, rock band freaks; Negativland.. It is called Our Favorite Things. It was quite fun to watch. They are into recycling music, video, visual art etc. and creating art the quite blatantly comments on the world around them. I like them...they are smart, funny and talented.
If you know Toronto composer, performer John Oswald you will often hear his name come up when Negativland are mentioned and vice versa.
Then...I went and explored negativland (and John) on Youtube for a bit...did find one decent interview with one of the Negativland guys...you can find that one yourself.
