While based in the United Kingdom 1975 to 1985, he was a frequent conductor with various London orchestras and appeared internationally with orchestras in Iran, Israel, Japan, the Soviet Union and the United States. His early compositions evoke the work of Aram Khachaturian, while his ''oeuvre'' as a whole is heavily influenced by Armenian folk and sacred music.
He has made some 100 recordings with RCA, Philips, EMI, ASV, and others.
