In our first night, even thought we were dead tired, we went to Antología Flamenco Show in Avenida Las Americas. The tickets were available in the door, but we bought the tickets online in advance from below website, while we were still in Netherlands; http://www.flamencotickets.com/antologia-tenerife
The duration of the show was almost two hours. They have 25 performers, I guess 10 male, 10 female dancers and 5 singer, unfortunately I am not certain L I do not want to spoil the show, thus I will not go into every detail, but it was magnificent. I fell in love with Flamenco all over again. The costumes, dancers, choreography, singers were amazing. The passion of the dancers and the lightening blew our mind. I do not think if I can watch better flamenco show ever in my life. One important tip, the stage was a little high, so the first two rows may be the best option to enjoy the show.
