The marimba was exported from Africa around the 16th century and has been popularized by either Western classical concert instruments, jazz/Latin jazz, or as Latin American folk instruments. For some reason or another it was Central America that really embraced it. From Southern Mexico to Nicaragua you can find traditional marimba street musicians in just about every larger city square (almost like the mariachi in Mexico). I’m not sure about South America, but from what I understand it extends down there also. However, the marimba is especially popular in Guatemala, to the point where bands like Marimba Orquesta Gallito have become a national symbol of tradition and culture. These larger marimba bands can incorporate any genre of music from traditional folkloric songs, mambos, to even a form of big-band Discos Fuentes style cumbias (which is pretty much the focus of this article). Almost like the accordion in Colombia and the guitar in Peru. I threw in a few Colombian cumbia standards for good measure. Also, Marimba Chiapas is from the southern Mexican state of Chiapas, which is just as much geographically and culturally similar to Guatemala than Mexico itself. Enjoy!
Peep the comment section, Sports Casual @ futurefunk.net put up a cool ass video of some Mexican kids jamming out to the marimba in the state of Oaxaca. Also he supplied this awesome pick of a marimba band for hire. God I miss Mexico.
