The early 1990s saw the emergence of many Macedonian pop-rap artists influenced by the then-popular MC Hammer and Vanilla Ice. These artists included for example the female solo singer Ena Veko, who released the LP "Bubački i gradski dzverki," and the duo Lastovica, which consisted of Robert Sazdov and Vlado Janevski, who later became a solo pop singer and represented Macedonia in the Eurovision Song Contest in 1998. Behind most of these successful pop-rap acts was the prominent Macedonian composer and producer Toše Pop Simonov. The group Nulta Pozitiv was formed in parallel. Gradually, they became more mainstream and popular across the country, especially after recording the rap track nicknamed after the famous Macedonian folk song "Otvori go Pendžerčeto" ("Open the Window"). It featured an unconventional refrain for a rap song sung by the notable folk music singer Mirko Mitrevski. They released an album titled Transfuzija. Later, another pop-rap artist named Kristijan Gabrovski emerged from Prilep and was nicknamed Risto Bombata after Afrika Bambaataa. He and his backing band became very popular across the country for their mix of rap, pop-rock and pop-folk. In the mid-1990s, an offshoot of Nulta Pozitiv, named Attack, was the harder-sounding group which released the famous song "Atentatot na Kiro" after the assassination-attempt on the then-President of the Republic of Macedonia Kiro Gligorov in 1995. Later, one of the former Nulta Pozitiv members, Darko Dimitrov rose to a prominent Macedonian composer and producer. Dimitrov also worked with the late 1990s/early 2000s pop-rap artists such as Vrčak and Ugro.
