Invisible

Invisible was an Argentinian band playing a mix of blues, prog/art/psychedelic rock and jazz, active from 1973 to 1977. They were formed as a trio in Buenos Aires by Luis Alberto Spinetta (after the breakup of Pescado Rabioso and the release of their last album, Artaud), in October 1973. The original Invisible lineup was completed by Pappo's Blues' on and off rhythm section, Carlos "Machi" Rufino (bass, backing vocals) and Héctor "Pomo" Lorenzo (drums).
Their selftitled debut was released in 1974. From 1976 until their breakup a year later, the band expanded into a quartet with the inclusion of guitarist Tomás Gubitsch, and the release of two more albums of which the third and last, the 1976 El jardín de los presentes, is considered the best and a classic, Argentinian rock album. In early 1977, the band called it quits after "musical differences".
