On the stage Lux Perpetua is a characteristic combination of percussion galloping, fast riffs, melodic solos, ubiquitous, clandestine bass and high vocal – basically everything that power heavy metal fans like most. Aether is a Polish band playing epic melodic death metal founded in 2015. They are inspired by Wintersun, Blind Guardian or Wolfheart. Optical Sun, founded in early 2017, will close the line-up this evening. The idea from the first common jam was simple – they play slowly and hard. The result is instrumental music, which is a combination of sludge, stoner and doom metal. All this in a dark atmosphere of film lyrics about devils and other marauding spells. Nuclearwinter, which closes the lineup, is a thrash metal band inspired by the achievements of Slayer and the Big Three German thrash metal bands, i.e. Sodom, Wizard, Destruction.
