Street Performers - Opera

I completed the Camino Frances on June 23, 2013. On the 24th and 25th, I heard an outstanding performance of Opera by a trio (two men and a woman), who were situated under the arch (Arco de Xelmirez) as one enters the Plazo Obradoiro. The crowd they drew each night was amazing, crowding the street and the stairway, leaving barely room for people to walk through.

Would anyone be able to tell me the name of the group and perhaps a website. I should have purchased their CD, but I just didn't think of it. thanks, Bob
