The ancient Celtic cultures believed that, during the transition period from the end of the harvest to winter, the border between the world of the living and the world of the dead became blurred. Bonfires, masks and rites helped to ward off spirits. Later, the Christian calendar added All Saints' Day, with the eve being called in English “All Hallows' Eve”; this expression gave rise to the word 'Halloween'. Meanwhile, the world kept turning. Successive waves of Irish and Scottish immigration took the tradition to the USA, and it was returned to the old continent in a transfigured version, via Hollywood. For all these reasons, it makes sense to add to the pumpkins and “trick or treat” a soundtrack on a global scale, crossing settings of fantasy and suspense. Homer's Odyssey inspired Robert W. Smith. Andrew Boysen Jr. wandered through cinematic plots in a small symphony. John Mackey recovered the Japanese imagery of the tsukumogami; objects that acquire a spirit and life of their own. This Halloween eve concert ends in Vienna, with a devilish waltz that challenges the classic irreverence of the young musicians of the Escola Profissional da Metropolitana. Programme. R. W.
