La Llorona is a traditional song in New Mexico, often played around the time of Halloween and Dia de Los Muertos. Some people on the live-stream have asked Ronen to play Norteno music, and this could be considered a Norteno song. I think Ronen's chromatic ending adds a lot to this version. If you want to learn to play it, there are lots of versions of this sheet music free on-line. And there are lots of interesting stories about the character La Llorona-- the weeper or crying woman. Enjoy!
