Q:A friend asked me to answer this question: What is the last name of the person whose first venture was written in a form which Bush thought acceptable to the general British public?, using the article: The postwar period also saw the beginning of Bush's 20-year involvement with grand opera, a genre in which, although he achieved little commercial recognition, he was retrospectively hailed by critics as a master of British opera second only to Britten. His first venture, Wat Tyler, was  written in a form which Bush thought acceptable to the general British public; it was not his choice, he wrote, that the opera and its successors all found their initial audiences in East Germany.  When eventually staged in Britain in 1974 the opera, although well received at Sadler's Wells, seemed somewhat old-fashioned; Philip Hope-Wallace in The Guardian thought the ending degenerated into "a choral union cantata", and found the music pleasant but not especially memorable. Bush's three other major operas were all characterised by their use of "local" music: Northumbrian folk-song in the case of Men of Blackmoor, Guyanese songs and dances in The Sugar Reapers, and American folk music in Joe Hill –  the last-named used in a manner reminiscent of Kurt Weill and the German opera with which Bush had become familiar in the  early 1930s.The extent to which Bush's music  changed substantially after the war was addressed by Meirion Bowen, reviewing a Bush concert in the 1980s. Bowen noted a distinct contrast between early and late works, the former showing primarily the influences of Ireland and of Bush's European contacts, while in the later pieces the idiom was "often overtly folklike and Vaughan Williams-ish".  In general Bush's late works continued to show all the hallmarks of his postwar oeuvre: vigour, clarity of tone and  masterful use of counterpoint. The Lascaux symphony, written when he was 83, is the composer's final major orchestral statement, and addresses deep philosophical issues relating to the origins and destiny of mankind., what would be the answer ?
A:
Bush
