After World War II, Panufnik moved to Kraków where he found work composing film music for the Army Film Unit. Some of this inevitably was for propaganda films; Panufnik later recounted how for one film, "The Electrification of the Villages", the director was unable to find a house without a supply of electricity, and had to demolish pylons and remove infrastructure to film it being built. Panufnik accepted the post of Principal Conductor with the Kraków Philharmonic Orchestra. He reconstructed some of his music that had been lost, starting with the "Tragic Overture" which was still fresh in his mind. Encouraged by this he also reconstructed his Piano Trio and "Polish Peasant Songs". However, his first symphony did not prove so easy and, disappointed with the result, Panufnik decided that he would thereafter concentrate on composing new works.
