Leonskaja was born on November 23, 1945, in Tbilisi, Georgia, to Russian parents. She was an exceptionally gifted child, giving her first concert at 11. She studied music at the Moscow Conservatory and, while there, won prizes in several prestigious international competitions, including the Queen Elizabeth, Marguerite Long, and Enescu. Leonskaja was soon noticed by Richter, and the two developed what would be a lifelong friendship, often appearing together in duet concerts. In 1978, she emigrated to the West, settling in Vienna. Her debut at the 1979 Salzburg Festival was a great triumph, after which she quickly established a reputation that yielded invitations in the next decades from the leading orchestras abroad, including those in New York, Cleveland, Los Angeles, London, Berlin, Leipzig, and Hamburg.
Leonskaja's recordings were drawing acclaim as well: her 1990 album of Brahms' sonatas won Belgium's prestigious Caecilia Prize. In 1995, Teldec released what would be one of Richter's last recordings, duet sonatas by Mozart and Grieg, with Leonskaja. Richter died two years later. In the new century, Leonskaja has been very active on the concert scene with numerous appearances at major concert venues. She debuted at Carnegie Hall in 2006 with Kurt Masur leading the London Philharmonic Orchestra in an acclaimed performance of the challenging Prokofiev Piano Concerto No. 2. Leonskaja earned the Solo Recording of the Year in 2014 from the International Classical Music Awards (ICMA) for the album Paris, on which she performed works by Debussy, Enescu, and Ravel. In 2019, she joined the Artemis Quartett on a recording of Shostakovich's piano quintet, and the following year, Leonskaja was awarded the IMCA Lifetime Achievement Award. Signed once more to the Warner Classics label in 2021, Leonskaja issued a recording of Mozart's complete piano sonatas in 2022. ~ Robert Cummings & Keith Finke, Rovi
