This is a traditional song (canto) sung in the Nahuatl ("Aztec") language. It is sung in a traditional "round" style (meaning it repeats). The featured version is by Tonana (aka Claudia Martinez) of Mexico City, and can be found in the above pictured CD. An alternative version can be heard below. Nimiztlazotla is "I Love You" in the language, also mentioned over and over again is No Yollo or My Heart. Enjoy.
