The Argentinean Luis Pescetti is author of many children’s books with a sharp and provocative sense of humour, an activity that he came to through his career as a music therapist and educationalist. In the 1990s, with the backing of Unicef, he designed a number of publications for teachers regarding the educational use of humour and music. Today he will talk about the role of humour in literature with writer and journalist Daniel Samper, who has written a range of critical, and comical, books.
