"That's why I don't really like to use the words avant-garde anymore. I don't really believe in them right now. They don't take in enough variety.
Avant-gardes get middle-aged; they become the establishment. When one goes to the Brooklyn Academy of Music, for instance, one is likely to see the work of artists who belonged to the avant-gardes of the 1960's and 70's and early 80's. Some are perfecting what they've already done. A few keep on experimenting, while some are being better paid to calcify than they ever were to innovate."(NYTimes.com|The Avant-Garde, Rarely Love at First Sight)
