Many of the original members of the group attended the Escuela Elemental and the Escuela Secundaria of the University of Puerto Rico, an institution noted for its progressive and experimental teaching approaches. Vocalist/bassist Willy Rodriguez commented, "It is a school in which you are allowed to decide a few things on your own, you have free time between classes you can do your own things, and there is a lot of musical culture in the school. It tends to allow you to explore your artistic interests ... There was always an air of liberation, of thinking on your own. I think that influenced a lot in what we do today musically and ideologically." Group members Boris Bilbraut, Willy Rodríguez, Eliut González, Juan Costa, and Ivan Gutiérres began jamming together in 1996, bonding over a shared interest in reggae music, particularly Bob Marley. These rehearsal sessions took place in El Hoyo, a neighborhood in the San Juan metropolitan area.
