Our events in the GREAT!CLSX series begin at 19:30 with a speech by an interesting personality from the world of art or science. For the concert on May 9, 2022, we have invited the New York philosopher and musician David Rothenberg to talk about a topic that we are all familiar with, but about which we usually know little: "What Birds Sing". In this interview, David Rothenberg explains how his interest in birdsong developed and uses a few examples to explain the meaning behind the chirping.
