They call it the “orange feeling.” Founded in 1971 by two high schoolers and a concert promoter, the annual music and culture festival Roskilde is hosted in the Danish town it’s named after about 18 miles west of Copenhagen. With a population of 53,354, Roskilde is the 10th largest city in Denmark, but for one week every summer over the past five decades, over 130,000 visitors descend upon the idyllic festival grounds for seven days of camping, music, art, food, and beer. Lots of beer.
