Departing from the usual relationship between poetry and animation in which the latter illustrates the former, this animation may be said to exist in dynamic tension or conversation with the text and music. The director, Michael Fragstein of Büro Achter April, told me in an email that his animation came first, and the German-Congolese jazz singer Lisa Tuyula wrote her spoken-word composition in response, following which Marc Fragstein wrote the music that ties it all together.
While I think this was intended more as a music video than a poetry video, the ekphrastic approach is one that poets and animators ought to consider experimenting with.
