 The chief executive , Brian McMaster , did not appoint a replacement to Geliot as principal director during the 1980s , preferring to engage guest producers . Boyd mentions <unk> <unk> 's Eugene <unk> ( 1980 ) among the successes and <unk> <unk> 's Carmen ( 1983 ) and Ruth <unk> 's Don Giovanni ( 1984 ) as productions that received more mixed responses . Sir Charles Mackerras , the conductor for Don Giovanni , was open in his contempt for <unk> 's production . Harry <unk> 's <unk> ( 1981 ) was condemned by The Daily Telegraph as " a piece of Marxist <unk> " making " political sport " of Beethoven 's work . McMaster was thought by some too inclined to favour radical eastern European directors : Jonathan Miller , a leading English director , commented that he did not intend to take Bulgarian nationality , although it was " a must before Brian pays any attention " .
