Their very first recording was on a local, independent label, but their first commercial release was "Libres y Locos" in 1998. It immediately caused waves in the Spanish language rock community, as it combined rap-style lyrics with a ranchera attitude. The single from this album, "Dormir Soñando," had some airplay on MTV en Español but did not become a hit on radio until it was covered by Los Chicos del Barrio. Their second album, "Chuntaros Radio Poder",(2001) expanded the musical mix, and the rap element faded. This album began with wide mix of styles from those reminiscent of the rock of Led Zeppelin and Pink Floyd, but with heavy Latin American rhythms from norteño to cumbia and vallenato. the album produced the alternative hit, "Chúntaro Style".
