"All [Bush's] operas deal with things that actually happened, the message being contained in a judicious selection of fact, the music aimed at the heart before brain." (en)
Bush's First Symphony:
"In this Symphony, the composer's intention is to evoke the feelings of the men and women of Britain during the 1930s. There is no programme of events depicted; the three main movements are more in the nature of mood pictures, each an expression of the prevailing mental and emotional atmosphere of the social movement of the time."
