Jose Nieves (Rakim) and Kenny Vazquez (Ken-Y), both from Gurabo Puerto Rico, with only 2 years of experience, have turned into one of the most important duos in Reggaeton, far surpassing their competetion. By the time they debuted in the compilation album "Warriors 4" most of the established duos in Puerto Rico were starting to break up (such as Héctor y Tito, Baby Rasta y Gringo and Karel y Voltio for example). Their debut song was not a big hit but they were quickly compared to the more famous at the time Zion y Lennox, refering to the way that one of them has a nice singing voice (Ken-y, Zion) and the other one raps (Rakim, Lennox).
