Warwolf opened the night with a roughly one-hour set as Rock Time Production celebrated their 20th anniversary with a heavy metal concert at Harmonie in Bonn. The Cologne-based band, which boasts over 20 years of history, delivered an enjoyable performance of throwback, ’80s-style heavy metal with their five-piece lineup featuring a solid rhythm section, two guitars, and vocals. They had no trouble setting the tone for the evening, quickly raising the energy in the room and winning over the audience.
