I went down a rabbit hole about 10 yrs ago and got into Argentine rock nacional. At the behest of an old gf who was a Porteña(from Buenos Aires). Music has never been the same since.
Probably the greatest band ever in Ibero-American rock: Soda Stereo. And almost unknown amongst English-speaking music fans. Gustavo Cerati went on to a highly-successful solo career after Soda Stereo went on hiatus.
Luis Alberto Spinetta was known as Argentina's Dylan.
Another rabbit hole I went down. Spinetta was part of Almendra, Pescado Rabioso, Invisible, Spinetta Jade, and a long solo career before he passed away in 2012.
