In the 1970s, a lot of critics didn't understand video. I got a lot of bad reviews. But film-makers didn't understand what we were doing, either. There were actual fistfights between film-makers and video-makers. I was witness to one.

I don't think the critics could understand what we were doing.

As for literary criticism in general: I have long felt that any reviewer who expresses rage and loathing for a novel or a play or a poem is preposterous. He or she is like a person who has put on full armor and attacked a hot fudge sundae or a banana split.

When you're making video, you're giving structure to time, which is what a composer does.

I came of age at the end of the 1960s, just when video was also coming into the world. Companies such as Sony and Panasonic were starting to market it and we artists immediately knew how it could be used.

Sociological critics are waste makers.
