 How did this happen? Well, it's a long story. Here to help us out is Alejandro Madrid. I'm an associate professor of Latin American and Latino studies at the University of Illinois at Chicago. Okay, time for a little Son Jarocho 101. The Son Jarocho is part of a larger complex of music in Mexico, the complex of son music. Son draws from Spanish poetic forms and is played on different string instruments with roots in medieval Spain.
