Bolivian rock band of the late 1960's to mid 1970's. They started as a beat, largely covers, band mixing hard rock, blues and psychedelic influences, issuing a few singles. They went through many styles during their history, later reinventing themselves as an experimental progressive rock outfit with the album "Gusano Mecánico". The Climax LP is widely regarded as a pinnacle of Bolivian prog alongside the the debut by Wara.
