It's the US band's first performance in Europe for 10 years, and follows the launch of ninth album The Great Divide last year. ProgPower promoters say: "It's been a long-time wish to announce the addition of Enchant. With over 25 years of experience, we're looking forward to them playing. Adding them is the best way to complete 2015's lineup."
