I Visited this venue for the first time and I was impressed by the organisation despite the number of people at the concert of Rodrigo y Gabriela.
There were enough air and never felt stifling thanks to the good air implant.
Also the 4 bars make the queue easier and faster.
3 STARS only due to the rudeness of the security person (1 man 1 woman at right of the stage) when I gently asked, after the concert, if possible to quickly congrat with the artists. There were very rude and aggressive. Furthermore sarcastic with me that only asked kindly a simple question.
These people clearly don't know much about art and artist but are more confident working in disco club or alcohol party as bouncer.
Very sad end of the day.
In fact when I went mortified to the left part of the stage, asking the same question, the 2 guys there simply explained that this was not possible and that only with a pass the access is permitted. Simply using politeness and explaining people things, treating them as person and not robots.
Will think about it, in case another event of an artist I like, better to go to theatre where likely find people who love and practice art and beauty
