La Gusana Ciega (Spanish for "The Blind She-Worm") is a Mexican alternative rock and pop-rock band composed of Daniel Gutiérrez (voice and guitar), Germán Arroyo (drums), and Luis Ernesto Martínez "Lu" (bass).
The band's origin dates back to the late 1980s when the original trio formed by Daniel Gutiérrez on vocals and guitar, Manuel Leyva on bass and Edwin Sours on drums (the latter being replaced by Germán Arroyo after a couple of years) began to establish themselves in Mexico City's underground rock scene.
The band added guitarist Jorge Vilchis (ex-member of Guillotina) the following year, which contributed to the evolution of a more characteristic sound, reflected in their second studio album, Superbee.
Having gained considerable popularity, the band toured Mexico and select US cities in 2000, culminating in the release of their live album, lagusanaciega.
In early 2005, they announced a reunion tour with the notable substitution of Martínez, Cosmonova's bass player, for Leyva.
