Her performances were noted for their musical intelligence and sophistication.  Her singing was admired by several important composers, including Benjamin Britten, Paul Hindemith, and Darius Milhaud.  While her performances, both live and on radio/disc, were mainly from the concert repertoire, she did perform in some broadcasts of operas on the radio and in the 1931 world premiere of Healey Willan's ballad opera "Prince Charlie and Flora".  In 1984 she was awarded the Canadian Music Council Medal. The International Composers’ Guild was an organization created in 1921 by Edgard Varèse.

However, the greater part of his career was spent with the Agence France Presse, which he joined as a senior editor in 1950.  He would spend thirty seven years with the AFP, serving as Manila bureau chief from 1962 until 1987.  Benigno maintained extensive ties with France.  Fluent in French, he studied at the Institut des Sciences Politiques and was awarded the French Legion of Honor in 1989.

Franz Ignaz Beck (Mannheim, February 20, 1734 – Bordeaux, December 31, 1809) was a German violinist, composer, conductor and music teacher who spent the greater part of his life in France, where he became director of the Bordeaux Grand Théâtre.  Possibly the most talented pupil of Johann Stamitz, Beck is an important representative of the second generation of the so-called Mannheim school.  His fame rests on his 24 symphonies that are among the most original and striking of the pre-Classical period.  He was one of the first composers to introduce the regular use of wind instruments in slow movements and put an increasing emphasis on thematic development.  His taut, dramatic style is also remarkable for its employment of bold harmonic progressions, flexible rhythms and highly independent part writing.
