The performance linked above was "Difficult Listening Hour" from "The Kitchen Presents Two Moon July" television show and was from the UbuWeb Film and Video page. The page states:
UbuWeb is pleased to present dozens of avant-garde films & videos for your viewing pleasure. However, it is important to us that you realize that what you will see is in no way comparable to the experience of seeing these gems as they were intended to be seen: in a dark room, on a large screen, with a good sound system and, most importantly, with a roomful of warm, like-minded bodies.And then they suggest that you buy the films and videos of the artists represented, as well as that you go to see the performances in venues near you. I live in a small farming community in the middle of nowhere in south Texas. This is as good as it gets for a while for me. But you...? That's another story, isn't it? Do what you can.
However, we realize that the real thing isn't very easy to get to. Most of us don't live anywhere near theatres that show this kind of fare and very few of us can afford the hefty rental fees, not to mention the cumbersome equipment, to show these films. Thankfully, there is the internet which allows you to get a whiff of these films regardless of your geographical location.
We realize that the films we are presenting are of poor quality. It's not a bad thing; in fact, the best thing that can happen is that seeing a crummy shockwave file will make you want to make a trip to New York to the Anthology Film Archives or the Lux Cinema in London (or other places around the world showing similar fare). Next best case scenario will be that you will be enticed to purchase a high quality DVD from the noble folks trying to get these works out into the world. Believe me, they're not doing it for the money.
