The Mitjans and Petits choirs of l'Orfeó Català present the cantata De qui és el bosc?, with music by Josep Ollé and libretto by Marc Donat, commissioned by the Palau de la Música based on the one prepared four years ago by the children's choir El Virolet dels Lluïsos de Gràcia in its summer house, with the same title and in musical format. It is an adaptation of the youth novel by Mercè Canela i Garayoa, published for the first time in 1976 by the La Galera publishing house.
