Metaklapa is a Croatian a cappella metal band that interprets songs by Iron Maiden without any instruments at all, but with brilliant polyphonic vocals. Actually, “Klapa” describes a musical group that sings passionate and upbeat, polyphonic Croatian a cappella folk songs. This centuries-old singing style is an UNESCO-listed intangible heritage and comes mainly from Dalmatia and southern Croatia. All six members sing in several Klapas and have been cultivating this style for years. And all six are sworn metalheads and worship Iron Maiden. Each has their own personal history with this band and their songs. Now, for the first time, they combine their singing tradition with their passion for heavy metal and hard rock and they believe: Heavy Metal and Klapa, that fits! The music of Iron Maiden is strongly based on vocal melodies, and these are the main part of Klapa singing, it is less about rhythm. Metaklapa manages to keep both the traditional characteristics of Klapa singing and the metal character of the songs.
