An experiment with language. Is it an object cultivated in poetic laboratories where entry is locked for mere mortals? And what do language scholars think about it? Specialists in language and literature studies interested in linguistic innovation and experimental poetry will find answers to these questions in Vladimir Feshchenko’s book. The study investigates various strategies of radical linguistic creativity in Russian and American experimental writing of the 20th century and explores cases of contemporary ‘language-oriented’ and ‘trans-language’ poetry. It is a comparative examination of two national avant-garde cultures, but also a juxtaposition of the relationships that Russian and American avant-garde poetics had with linguistic ideas of their times. The monograph may serve as a wonderful introduction to the entire field of ‘linguistic poetics of the avant-garde’.
