From Chile too:
Los Tres and
Kudai (pop).
Coming back to the 80's, I think the following can be representative of the high level achieved in that decade (the so-called "
Golden Age" of Spanish-language rock and pop by many music critics):
Jimmy Page and Robert Plant? No.

Just three guys from Madrid (band
Leño) in 1983. Song says: "
Madrid is a sh**, where not even the rats can live".
In 1984,
Gabinete Caligari, a band from Madrid too, published this song (there is no official video, but I think the beautiful Gisele Bundchen is an excellent choice to accompany the beautiful music

):
Soda Stereo, from Argentina, made this song in 1988, with influences from gothic rock and The Cure.
En la ciudad de la furia ("
In the City of Fury", or, in other words, Buenos Aires
