Alexei Semenovich Kozlov was a Russian saxophonist, composer, bandleader and writer who helped shape Soviet and Russian jazz from the cafe underground of the 1960s to a professional jazz-rock tradition that reached concert halls at home and abroad. He died in Moscow on 25 September 2026 at the age of 90, at home after a short illness, surrounded by family. His press secretary and Russian outlets including RIA Novosti, Izvestia, Komsomolskaya Pravda and Kommersant reported the news the same day. He would have turned 91 on 13 October.
Born in Moscow on 13 October 1935 into a musical household, Kozlov grew up with sound as a family craft. His mother, Ekaterina Tolchenova, conducted choruses and taught music theory. His father taught at the Moscow Pedagogical Institute named after V.I. Lenin. His maternal grandfather, Ivan Tolchenov, sang on the opera stage and in church choirs. Kozlov finished a music school as a pianist in the mid-1950s, then taught himself the tenor saxophone, later making the alto and soprano his principal voices. The nickname "Kozel na sakse" stuck for decades and became the title of his 1998 memoir.
In 1959 he formed a quintet with trumpeter Andrei Tovmasyan. Festival work followed quickly, including Tartu in 1960. From 1961 to 1966 he was a central figure at Molodyozhnoye, Moscow's pioneering jazz cafe-club, opened in a political moment when foreign guests needed a showcase and young players needed a room. With Vadim Sakun's sextet he took part in the first Soviet jazz group to appear at a major foreign festival, Jazz Jamboree in Warsaw in 1962. Parallel to night work he trained as an architect, graduating from the Moscow Architectural Institute (MARKHI) in 1962 and working for several years at the Institute of Technical Aesthetics. Architecture gave him a day profession while jazz remained, for a long stretch of Soviet cultural policy, a contested art.
Through the late 1960s he moved through Moscow's fragile club circuit, including Rhythm and Pechora, and spent 1966 to 1968 in Yuri Saulsky's VIA-66 orchestra, spinning out a quartet with Igor Bril and others from that band. In 1973 he founded Arsenal, widely regarded as the first professional jazz-rock ensemble in the USSR and later the country's leading fusion band of its kind. From 1976 Arsenal was attached to the Kaliningrad regional philharmonic, which gave the group an official touring and recording path after years of semi-underground existence. Melodiya released Arsenal albums that circulated widely; the 1983 set Svoimi Rukami (With Our Own Hands) was later reissued in the United States. Kozlov wrote roughly a hundred jazz pieces and kept rebuilding Arsenal's lineup and style, from rock-opera and progressive colours to fusion, breakbeat flavours and later chamber collaborations.
He was never only a bandleader. In the 1990s he pursued "third stream" programmes with Yuri Bashmet's Moscow Soloists, pianist Vyacheslav Gorsky, the Shostakovich Quartet and the Moscow Philharmonic Symphony Orchestra. He hosted television series such as All That Jazz on ORT (1994) and Improvisation on a Theme, issued educational CD anthologies on jazz history and instruments, and delivered lecture-concerts, including at the Moscow International House of Music. He published Rock: Origins and Development (1997), the memoir Kozel na sakse (1998), Jazz, Rock and Brass (2005), Rock Through a Jazzman's Eyes (2008) and Jazzist (2011). American journalist Hedrick Smith devoted part of a chapter in The Russians to Kozlov and Arsenal; Frederick Starr discussed him in Red and Hot; Vasily Aksyonov wrote him into the novel The Burn. In 1995 Arsenal toured the United States with Georgian singer Tamara Gverdtsiteli and played Carnegie Hall. In 2021 Andrei Airapetov's feature documentary Jazzist put his life on cinema screens.
Recognition arrived in stages that mirrored Russia's own cultural thaw and official rehabilitation of jazz. He was named Honored Artist of the RSFSR in 1988 and People's Artist of Russia in 2003. The Moscow City Duma gave him an honorary diploma in 1999. In February 2026 he received the Order For Merit in Culture and Art. A Moscow club bearing his name, founded in 2012 with his consent though not under his ownership, was ranked among the world's best jazz clubs by All About Jazz in 2019. He served as president of the Alexey Kozlov Foundation supporting contemporary instrumental music. Weekly Arsenal concerts continued into late 2023; in 2024 he announced he was ending performing career because of age, with saxophonist Anna Korolyova succeeding him in the band.
Kozlov spoke often about nonconformism as a jazz ethic. In a 2014 Moscow 24 interview he said one of the properties of a jazz musician is nonconformism, calling the improviser an unpredictable egoist whom states of any stripe tend to distrust. In a 2016 NSN conversation he argued that once the taste of prohibition vanished from Russian jazz, an elusive quality vanished with it, even as technical standards stayed high. He married Lyalya Absalyamova, an English teacher; he had a son, Sergey, from an earlier marriage. Colleagues including Igor Butman answered his death by saying jazz had been orphaned. What remains is a recorded catalogue, a named club and foundation, and the memory of a musician who turned a contested saxophone into a public language for several generations of Russian listeners.

In their own words
“One of the properties of a jazz musician is nonconformism. This is always an egoist, an unpredictable person, an improviser. That is why jazz musicians are disliked in any state, under any system.”
Moscow 24 interview, 21 January 2014
“I want to share the thought that contemporary jazz, which no one forbids in Russia, continues to develop along international lines and stands at a fairly high level compared with many Western countries. Only the taste of prohibition, which in Soviet times created a special, elusive quality, has completely disappeared from domestic jazz. And that is a pity.”
NSN interview on International Jazz Day, 30 April 2016
“I was so immersed in my own work that there was no time for pop.”
Moscow 24 interview on listening habits, 2014
“Of course not. I myself now produce the goosebump effect on others.”
Moscow 24, asked whether recent concerts still gave him the thrill he felt hearing Joe Temperley in 1957
“Nonconformists, to whom I always belonged, despised the twist with terrible force.”
Moscow 24 interview, on Soviet-era official entertainment music
“Today jazz has been orphaned.”
Igor Butman to RIA Novosti after Kozlov's death, 25 September 2026
“He died today, in the circle of family, at home, after a short illness. His wife reported this.”
Press secretary Victoria, quoted by Izvestia / KP, 25 September 2026
“I am a composer who plays the saxophone and invents melodies directly while performing.”
