The members of the group Bacilos are singer and guitarist Jorge Villamizar from Colombia, bassist André Lopes from Brazilia and percussionist: José Javier Freire from Puerto Rico.
The band was formed in the mid 1990s by three students of the University of Miami and was named after the Spanish word for bacillus. Originally a quartet, the band drew influences from Cuban folk singer Silvio Rodríguez and Argentinian rock singer Fito Páez. The band eventually became a trio.
The band announced that they would break up and completed their final tour in the United States on December 15, 2006, when they played at La Covacha, in Miami.
Their final live show was on February 21, 2007, at the Festival Internacional de la Canción de Viña del Mar, in Chile.
