I've recently been listening to a new album by the best band I've heard in ages, Boys From The Hill. Very powerful stuff and I commend it to anyone who might be interested.

One of the original songs on the CD is entitled 'Guitarra Armada'. Quoting from the sleeve notes:

An album kindly loaned to us by Gary Phillips of the Amigos provided the inspiration for this song. The album was a collection of songs set to a typical Latin Salsa, but the lyrics were quite deadly. The Sandinistas of Nicaragua had to educate a largely rural population to the tactics and techniques of guerilla warfare and this is how they succeeded.

This little piece of info caught my imagination. Can anyone shed some more light on this remarkable means of communication? Have any other groups or governments disseminated information through the manipulation of music?
