channel, and several days later on the main national channel as well. Perković during his career has cited Mate Bulić, Nightwish, Iron Maiden, AC/DC and Dream Theater as main influences. In 2009, a concert in the Swiss city of Lucerne was canceled after the Social Democratic Party called for an urgent statement on the issue of Thompson's concert, calling Perković a fascist. He was then banned from performing in Switzerland, after the Swiss Service for Analysis and Prevention (DAP) stated that his texts are glorifying the Nazi-affiliated Ustaše of the Independent State of Croatia.

Perković and his band's inclusion in Croatia's celebration of the national team's second place finish in the 2018 FIFA World Cup also garnered controversy and criticism. Perković's alleged glorification for the
