A difficult recommendation

For the moment I'm fighting my way through Monika Schmitz-Emans book Die Sprache der modernen Dichtung (1997, München: Fink Verlag) which contains some interesting discussion about modern poetry and especially the part "Positive und negative Schrift. Aspekte einer Poetik konkreter Dichtung" is inspiring. Here she clearly describe how concrete poetry is inspired from Kandinsky (1866-1944) and his distinction between abstract and concrete. Furthermore she describes how the barriers between the genres disappears as a direct result of concrete poetrys way of seeing the work of art just as a thing amongst other things.
