Sorry about the late response to your message. I don't have any licensing information on this track, but it's on Anfion, an old, defuncrt label. I am a big fan of the singer Saul Martinez and the composer Guty Cardenas. Frontera has several other songs by Martinez on Anfion, all but one written by Cardenas. In my private collection, I have many Saul Martinez albums on the Orfeon label, based in Mexico City. It was a major independnet laebel in its day and apperars still to be active, judging from its website which has contact information. Sadly, however, they don't list any available catalog albums under the artist page of Saul Martinez.
Good luck with the film.
I am an independent filmmaker living in Denver working on a documentary in Oaxaca, Mexico. Do you know how I can license this music track?
