Now I see some people bashing Spanish pop music/rock whatever. While Spanish is my native language I have to say, they are right on the money. Most of the popular stuff is dismal. But the same goes with English you have to go deeper than MTV Español or the radio. As far as I'm concerned if you get anything out of this thread is to listen to a band called Los Fabulosos Cadillacs. Not for everyone maybe, but that doesn't take away from the quality of their music. They started out as a ska band but over the years have evolved into their own, even collaborating with Celia Cruz at one point.
Another good band is Los Aterciopelados another very good band who started out as a punk band and has evolved over the years as well. Both of these bands have an extensive catalogue to explore.
Other bands I would recommend: Enanitos Verdes, Kinky, Molotov, and Zoe. All pretty popular but worthy listens. If I think of anything else I'll post it here. I never really delved much into Spanish rock since the bands out at the time were *so* fucking lame, but I'll see if I can find anything else.
