Although Mexico has had more than one Revolution when people say 'Mexican Revolution' they usually are talking about one that took place in 1910 - that seems to have produced some of the best corridos too - at least some of my favorites. For a good account of the 1910 Revolution I recommend 'Insurgent Mexico' by John Reed. Another good book on that subject was written by John Womack - Zapata and the Mexican Revolution. Fascinating part of history. I really feel like you will enjoy that CD set if you order it.
