For the new and the old, the wild and the innocent; Once in a Blue Moon Festival presents the full spectrum of what is going on in American roots music on August 24 at the Amsterdamse Bos. From heartbreaking americana to catchy new country, the festival welcomes all with a passion for American roots music. A full day of the best Americana, country, folk, blues & roots rock music on multiple stages in the stunning setting of the wooded area of the Amsterdamse Bos. It is so much more than just another music festival. It is about celebrating great songs. From well-known artists to undiscovered talents. A taste of American cuisine. It is warm, twangy stuff, full of finger-plucked guitars and gnarled voices like tires on a dirt road.
