Devilstone Open Air

Devilstone Open Air (aka "Velnio Akmuo" in Lithuanian) is a summer open air heavy metal music festival. It takes place annually since 2009 in the town of Anykščiai, in Lithuania. Devilstone Open Air has included performers playing black metal, death metal, power metal, thrash metal, sludge metal, doom metal, post rock, stoner rock, and progressive rock music genres. Music bands from Europe, North and South America, and Australia have performed in the festival. Devilstone Open Air is usually held in the mid-summer, around the third weekend of July.

Other activities
Next to live music performances, Devilstone Open Air has workshops, masterclasses, a club night called Rocktheque, sports tournaments, and other activities. The festival owns the rights to a one-of-a-kind growling/screaming/grunting competition MC Growl.

Controversy
In 2009 Lithuanian Association of Exorcist labeled the band Sepultura, who were announced to play at the festival, as ‘satanic’ based on their lyrics. Local church spoke against the festival’s choice of title. In 2010 Mayhem performed at the festival. After their performance, the local priest collected photographic evidence and went to the Ministry of Justice with a request to investigate the band's performance. The priest supported by a group of believers claimed that “Norwegian band Mayhem, that took part in the festival, incited religious hatred.” In 2011 the band Ondskapt performed at the festival. During the performance the band member Kim stepped out naked onto the stage creating a resonance within the society. In 2012 six Lithuanian towns held religious adorations for the festival’s audience and a faithful congregation prayed next to the festival gates.
