From Wikipedia:
The Argentine rock movement was truly one of the first non-English forms of rock to be commercially successful outside its own nation.
Argentine rock, which was the first kind of rock in Spanish ever to emerge in either Spain or Latin America, has a “founding trilogy” in 1967 with three mythical bands:
- Los Gatos (“The Cats”), similar to the Beatles, they disbanded in the 60′s;
- Manal, more of a blues / hard rock thing, first aligned with the Stones and later aligned with the heavy metal movement until the 80′s;
- Almendra (“Almond”) which was the real start of argentine progressive rock, also disappeared in the 60′s.
