Perković during his career has cited Mate Bulić, Nightwish, Iron Maiden, AC/DC and Dream Theater as main influences. His concert at the stadium was aired live on the state owned HRT Plus pay-per-view channel, and several days later on the main national channel as well. In 2007 he surpassed the 2002 concert at the Maksimir Stadium in Zagreb on 17 June 2007, with 60,000 people attending. On 15 September 2002, he had his largest concert to date at the Poljud Stadium in Split with about 40,000 visitors. In 1995 he returned to the Croatian Army and the 142nd Drniš Brigade, and became one of the first soldiers to enter the captured cities of Drniš and Knin during Operation Storm. He continued to write songs to raise morale during the war. In 1992 Perković held concerts throughout Croatia, and released his first album the same year. It was while he was defending his home village that Perković became inspired to write one of the most popular songs during the war 'Bojna Čavoglave' ( Čavoglave Battalion), which launched his music career.

He joined the Croatian National Guard where he was given the American Thompson gun, which became the nickname given to him by his battlefield comrades. In 1991, Croatia declared independence from Yugoslavia, prompting the Croatian War of Independence. He rarely saw his father, who worked as a Gastarbeiter in Germany and rarely came home. Perković was born in 1966 in Čavoglave (at the time SR Croatia, SFR Yugoslavia) to Marija and Ante.
