In June 2016, Berlin-based retro-rock band Kadavar—pioneers of modern psychedelic and stoner rock with albums like Abra Kadavar (2013)—performed at Rock Hard Festival, an annual event launched in 2003 in Gelsenkirchen, Germany, as a platform for heavy music emphasizing thrash, black, and death among 10,000 attendees at Amphitheater Gelsenkirchen. Their hour-long main stage set, captured professionally by Rockpalast, embodied the tour climax, where Christoph "Lupus" Lindemann's heavy riffs merged with Christoph "Tiger" Bartelt's drum power to spark euphoria under summer skies. Featuring tracks like "Doomsday Machine", "Living in Your Head", and "Creature of the Demon", this show highlighted their role in reviving 70s rock, turning the festival grounds into a realm of collective groove.
