The Mariachi performed very well, the only thing was that it was an outdoors event and people could barely hear them. If you are planning an event outdoors I highly recomend using microphones and amplifiers for them. Communication was all done through the phone, they never answered my e-mails (that worried me a little). But that said, they showed up on time and played their best. They walked around and serenaded our guests. I would defenitevely hire them again!
