In a word, fantastic!!!
In spite of the blurriness you see in the iPhone photo (hopefully Steve will include a decent camera at some point in his newest iPhone) the concert was very sharp indeed.
He started almost on time, around 9:30, under a clear, cool, moonlit sky and performed for almost 2 hours to a very enthusiastic Merida audience in the crappy Kukulkan baseball stadium. I kept thinking, it sure is nice of him to come here; I mean he is truly world class and here he is playing this dinky place. I also felt bad for the people up in the bleachers, who must have seen just a speck.
The music was absolutely perfect, as was the sound and simple lighting. The musicians had their moment in the middle of the concert, performing an extended demo of their percussion talents and doing a bit of Michael Jacksons' Thriller dance, complete with white gloves.
Juan Luis himself was friendly and his voice is just as good as 20 years ago, when he was first noticed by yours truly.
All in all, a great night out!
