Musical career

They formed part of the original members of DJ Eric Industry, alongside MC Ceja, Glory, Felo Man and his father TNT. Both Lito and Polaco were in the process of recording their debut solo albums entitled De La Calle Pa' La Calle and El Táltaro respectively, this last one has never been released. In late 2007 on a radio show it was announced that the legendary duo will return with a new album, La Institucion. On September 18, 2014, they announced their comeback, after 9 years.
Polaco

Polaco began his career in 1992 alongside Prieto Valdez on the CD called The Noise from DJ Negro. They both formed the duo Polaco & Prieto until Polaco and DJ Eric's crew started a lyrical war against DJ Negro and The Noise crew, and that was when Prieto broke from the duo. Prieto started a small war with Polaco after his song "Ellos Que Se Creen" which was featured on The Noise 7 in 1997. Polaco responded in the song "Que Vas Hacer" which came out on the production Gargolas 2 in 1999. Although having not gotten along with him for many years Polaco seems to have resolved his differences with Gringo even to the point of supporting him by making a guest appearance on Gringo's solo album El Independiente.
Awards

The duo's Mundo Frío album was nominated for Billboard's Latin Rap Album of the Year but lost to El General Is Back by El General.
