Spanish National Orchestra
Frühbeck was principal conductor of the Bilbao Symphony Orchestra from 1958 to 1962. During this time, the orchestra's manager persuaded Frühbeck to use a name that would more clearly indicate his Spanish identity. He subsequently took the professional surname "Frühbeck de Burgos" as his artist's name, to include the name of his birth city. He served as principal conductor of the Spanish National Orchestra from 1962 to 1978.
