I recall seeing Mariachi Los Camperos de Nati Cano in concert at George Mason University a few years ago. It was my first "sit down" and listen experience with Mariachi music. Several things struck me. First those cats had iron chops. Excellent musicianship and showmanship. After about an hour it became boring musically. Each trumpet played the same part, and each chart lacked any attempt at dynamics. It was full bore FFF from start to finish. No dynamics and no harmony. I had my fill.
The show was entertaining but I doubt I'll go back again.
