For this, the extraordinary 135 minutes long 15-year anniversary show that took place on the 28th of July on the historic open-air stage Dalhalla, built in an old quarry near the small Swedish village Rättvik, was captured on camera. Prominent guests included original HAMMERFALL line-up members Jesper Strömblad and Mikael Stanne, as well as ex-guitarist Stefan Elmgren, among others, which made the show unforgettable - also for the musicians themselves.
