Got a recommendation for El Horreo from Francis, and busted out laughing when this page loaded. I like all the bold colors and cool images of the site. Thanks, Francis!
I have a recommendation for you; it's an Argentinean band called El Horreo, who I heard by accident when I was in Buenos Aires. I never heard anything like they in South America. They are a bit odd and very pleasant listening.
Here are some El Horreo tunes. There are plenty more on their colorful and happy website. Check out their site. Cute Argentinian boys!
~ El Horreo - Primero Uno ~
~ El Horreo - Fondo De Omar ~
~ El Horreo - Te embarazo ~
~ El Horreo - Por Otro Dia ~
~ El Horreo - Y Si Estoy ~
To my ears, Francis' work is more pleasurable. You can stream or download his work at his Soundclick site. I love "La Hija del Diablo." His tune "Yayara" brings Fredo Viola to mind, and "Barrientos" has a fun Manu Chao flavor. I may be far off, but those are the alignments my head came up with just now. Enjoy!
