And you thought Umbria Jazz was only in the summertime! On December 30th the wintertime counterpart to Perugia’s summer jazz festival begins in Orvieto, another Umbrian city. This year’s edition is the seventeenth to be presented, and will be a five-day jam of the world’s best jazz musicans. Orvieto, sitting on its tufa-rock plateau, will open the doors to its best venues for the festival.
