Originally known as the Eazy Boys and also known as Los Lobos, the duo were notable for their confrontational diss tracks aimed at popular artists. Their track "Un Beso" was number-one in Honduras, Chile, Peru, and other countries.
Tracks of the group took shots at artists such as Wisin & Yandel, Don Omar and Hector & Tito. They collaborated with Alexis & Fido, Tito El Bambino, Nicky Jam and others on their 2015 album Los Cotiziados. They were active from 1988 to 2004, and made their return in 2007.
