"I composed EVOCATION under the influence of the student protests in Paris in May 1968, which I witnessed whilst taking part in Olivier Messiaen's composition course as a scholarship holder. But the idea to write a large work against war goes back to an earlier plan. lngeborg Bachmann's poems - which I have set to music in this oratorio - made it possible to put this into practice. 

One of my main concerns in this composition is "transition": Transition from sound to word, from noise to music and vice versa, transition from small to larger intervals, from wide-meshed to dense structures, transition in every possible manifestation. 

Further works on the CD, interpreted by the same musicians, give the listener the chance to follow the development of my sound spectrum up to the present day.“ Dieter Kaufmann
