I have been running a Latin Music Festival for four years and direct my college's Latin Ensemble. We have never had such a professional, accessible, and friendly group as Son Quatro perform. John and a couple of his percussionists made themselves available to my students for a workshop on Latin rhythmic style. During their evening performance, the band communicated very closely with our audience creating a very festive evening. Highest recommendations! We're already planning on having them back next year.
