As we look forward to next week's performances of Cruzar la cara de la luna, the first-ever mariachi opera by Jose 'Pepe' Martinez, it's time to get more familiar with mariachi as a musical form. Just what is mariachi, what are its roots, how has it developed and what has it to do with opera? Professor of Mariachi Studies at Southwestern College, classical and mariachi trumpet player Jeff Nevin has some answers for us and we think you'll find entertaining and interesting. Join Nicolas Reveles, the Geisel Director of Education and Outreach for this wonderful conversation.
