Aguaturbia's second LP "Volumen 2" (1970) is an essential album to understand the construction of what we know today as Chilean rock. The album is as raw and dynamic as their debut LP, featuring even heavier rhythms, distortion, and exceptional phased female vocals reminiscent of Jefferson Airplane. Comparisons with the Grateful Dead, Country Joe and the Fish and Led Zeppelin can be drawn. Splendid heavy psych and proto-stoner tracks make this album a pioneer recording in the history of South American rock.
