Dark Season Blues is an annual blues music festival in late October, at 78 degrees north in Longyearbyen (Svalbard) in Norway, and marks the beginning of the dark season when daylight and the sun is about to leave Svalbard for four winter months. The festival lasts four days, and features local, Norwegian and international musicians performing in most of Longyearbyen's venues. The festival is based on voluntary work in order to carry out the event. The economic goal is to break even, and any surplus is transferred to next year's festival.
