AC/DC JG Krokus Krokus to open for AC/DC! May 19, 2010March 13, 2017 admin Swiss rockers Krokus have long been likened to one of their biggest influences: AC/DC. It was a comparison that shadowed Krokus for years. But when the opportunity came for them to open for AC/DC’s U.S. tour back in 1981, Krokus dismissed the critics and rocked side by side with the legendary Aussie rockers. Nearly 30 years later, that opportunity has presented itself again. Krokus recently announced that they received an invitation from AC/DC to be the band’s special guest for their June 8 sold-out show at Stade de Suisse football stadium in Bern, Switzerland. So for those attending the show, be prepared for something nothing short of momentous.
