Last Saturday we went to the concert of Gustavo Dudamel and the Mahler Chamber Orchestra. It turns out that behind our town they installed a projector with a cooling system that caused a great noise. We could not hear anything from the first part (which is when the projector worked). Who can resort to installing an engine in the middle of a concert center? What a lack of professionalism !! Warned the technicians told us that they could do nothing. Outraged !!! A lost evening
