Zrinko, Mario and Jasmin started their friendship through music when they were in an elementary school in Virovitica, Eastern Croatia. Even then, they were making original music and experimented with recordings and sound production, despite the lack of the professional music equipment. Later, Zrinko and Mario went on to study music in Zagreb and Vienna, and Jasmin started to develop his woodcrafting skills by making his own instruments. During this time, the old friends played in different bands. Eventually, all of them ended back up in their hometown and started ZmaJ.
