Interesting read by Kenneth Fitzgerald.

“In music, an example of an axis extension was guitar feedback. Classically, this would be considered a “bad sound”. Now, as Jimi Hendrix playing “The Star Spangled Banner” at Woodstock, it’s not an instance of improving the ratio of “signal to noise”. The noise is signal. In graphic design, David Carson is the popular face of an axis extension beyond the modern, commercial standard. Or the extension is a debate point where, depending upon the viewpoint of the self, the Ability channel is pushed to either extreme. Whatever may come about, we will need a critical model that can encompass all possibilities, It needs to be as adaptable as design itself.”
