Blazhkov graduated from the conducting faculty of the
Kyiv Conservatory (1959), in the same year he became a diploma winner of the republican competition of conductors, worked as a conductor in the
Ukrainian State Symphony Orchestra. He corresponded with prominent Western musicians, including
Igor Stravinsky,
Edgard Varèse and
Karlheinz Stockhausen, and participated in the preparation of Stravinsky's tours in the USSR (1962). Then he studied at the postgraduate course of the
Leningrad Conservatory with Yevgeny Mravinsky (graduated in 1967). From 1963 to 1968, he worked as a conductor of the Leningrad Philharmonic. Already at this stage, as Sofia Khentova noted in 1965, "he established himself as an initiative performer of forgotten, little-known works". After a break of almost 30 years, he performed Dmitri Shostakovich's Second and Third Symphonies. He was dismissed by the decision of the Board of the USSR Ministry of Culture for performing avant-garde music. From 1969 to 1976, Blazhkov led the
Kyiv Chamber Orchestra, performing numerous works by composers of different eras and countries, from Baroque to modern Ukrainian. In almost every concert of the ensemble there were works marked: "Performed in Kyiv for the first time", "Performed in the USSR for the first time" or "Performed for the first time". By 1983 he began leading the Perpetuum Mobile Chamber Orchestra of the Union of Composers of Ukraine, with which he had performed numerous rare and forgotten works, including archival materials from the collection of the Berlin Singing Academy, taken out of Germany after
World War II, which were stored in Kyiv. He also continued to perform works by modern composers. In 1988–1994 he was the artistic director and chief conductor of the State Symphony Orchestra of Ukraine. Then he was illegally dismissed and left without a job, as a result of which in 2002 he emigrated to Germany. Blazhkov lived in
Potsdam, where he died on 7 January 2026, at the age of 89. ==Legacy==
