Welcome to El Salvador Musical, the online home of Revista de Música Salvadoreña y Latinamericana.

from their website:

Dedicated to the musical activity of El Salvador and Latin America. Its author is Salvadoran-American composer Carlos Colón-Quintana. Various collaborators also will participate in this virtual forum. Our principal emphasis is on música de arte [which I'm guessing is something closer to concert pieces/classical music]. However, we also will discuss folkloric music and important popular groups. Nevertheless, the focus will be from a cultural and serious point of view.

I thought Años (con texto de Nora Méndez) was particularly interesting. You can listen to a few of Carlos' pieces on the site.
