 A most memorable concert was performing Beethoven's 9th with a full choral, at the cathedral ruins of Antigua in 1952.During his tenure as director of the Guatemalan National Symphony Orchestra, and especially before the overthrow of President Jacobo Arbenz, Maestro Archila attracted the best musicians in Guatemala and from the Americas, and was able to create an orchestra whose music transcended political, economic, social and cultural boundaries.The orchestra and Andres Archila shared guest-conducting and solo roles when traveling to Mexico, (performing with José Pablo Moncayo), Chile (performing with Victor Tevah), and Colombia (performing with Guillermo Espinoza).
