The US Embassy in Argentina had this to say:
After a long hiatus, California punk rock band Face to Face performed in Buenos Aires for the first time on December 11th. Eight hundred fans packed El Teatrito and sang along with every single song from the band's new album, along with their older classics. Ambassador Anthony Wayne attended the energetic show.
Band leader Trever Keith thanked his enthusiastic audience, commenting that it had been one of the most electrifying concerts he had ever had. "Our first-ever South American tour gives us a whole new appreciation for the punk movement around the world. It doesn't matter where you are from, we love you all!"
