their availability outside that country was very rare until the release of the Brilliant box set "Historic Russian Archives Leonid Kogan Edition" Kogan was made a People's Artist of the USSR in 1964, and received the Lenin Prize in 1965. Kogan married Elizabeth Gilels (sister of pianist Emil Gilels), also a concert violinist. His son, Pavel Kogan (b. 1952) became a famous violinist and conductor. His daughter, Nina Kogan (b. 1954), is a concert pianist and became the accompanist and sonata partner of her father at an early age. Kogan died of a heart attack in the city of Mytishchi, while travelling by train between Moscow and Yaroslavl to a concert he was to perform with his son. Two days before, he had played the Beethoven Violin Concerto in Vienna. He was buried in Novodevichy Cemetery. Many speculate that Kogan played on all steel strings, though there is not an outright confirmation. While his close associates indicate he played on gut strings except for a steel 'e' string, it is most likely that he used different combinations over the course of his career. Instruments Kogan used two Guarneri del Gesù violins: the 1726 ex-Colin and the 1733 ex-Burmester. He used French bows by Dominique Peccatte. Kogan never actually owned these instruments; they were provided on loan from the Soviet government. Today they are worth more than US$4 million. Recordings Kogan formed a trio with pianist Emil Gilels and cellist Mstislav Rostropovich. Their recordings include Beethoven's Archduke Trio, the Schumann D minor, the Tchaikovsky, the Saint-Saëns, the Horn Trio by Brahms with Yakov Shapiro (horn), and the Fauré C minor Quartet with Rudolf Barshai (viola). Kogan later formed another trio with conductor Yevgeny Svetlanov (piano) and (cello). Kogan was the first Soviet violinist to play and record Berg's Violin Concerto. He also made a famous recording of Khachaturian's Violin Concerto with Pierre Monteux and the Boston Symphony Orchestra for RCA Victor (his American debut recording), a version still considered the most exciting reading of the work. Kogan recorded violin concerti by other Soviet composers, including the two by Tikhon Khrennikov. With Karl Richter, Kogan recorded J. S. Bach's six Violin Sonatas in 1972. There are more than 30 albums of his performances on the Arlecchino label. In 2006, EMI France issued a 4-CD box set ("Les Introuvables de Leonid Kogan") containing his concerto recordings for that label, all digitally remastered the
