The limit of tickets for the Argentine Performers concert series at Teatro Colon as been changed as of March 20 from four to two:
Tickets for all the concerts in this cycle can be collected on the Friday prior to the performance, from 10 am to 8 pm at the Teatro Colón ticket office, Tucumán 1171.
Tickets are given two per person until seating capacity (2,487) is reached.
There was a huge crowd around the building on March 13, and many were turned away without tickets. Hence, the change in policy. I was in line at 8:30am on Friday to obtain tickets for this Sunday's concert at 11:00am. All tickets are handed out within a couple of hours. They're for designated sections, not specific seats. If you want main floor, be in line at the Tucuman street door at least by 9:00am.
It's the same procedure to obtain two tickets for the Orquesta Estable and Orquesta Filarmonica concerts held at La Usina del Arte in La Boca.
