Born in 1989 on Sakhalin Island off the Pacific Coast of Russia, Julia Lezhneva's international career began with a bang when she caused a sensation in 2010 at the Classical Brit Awards in London's Royal Albert Hall with Rossini's Fra il padre at the invitation of Dame Kiri Te Kanawa. Just a decade later, she is discovering a broad repertoire with various orchestras, conductors, operas and oratorios. She made her highly successful debuts with the Berliner Philharmoniker in October 2019 and at the Musikverein Wien in December 2019. She returned to the Mozartwoche Salzburg in January 2020, this time under Sir András Schiff in Mozart's Le nozze di Figaro; in January 2023 she sang in Don Giovanni. In June 2023, she appeared for the first time at La Scala in Milan in Porpora's Carlo il Calvo.

In December 2020, she made her celebrated debut with the Symphonieorchester des Bayerischen Rundfunks under the direction of Herbert Blomstedt. Her debuts with the LA Philharmonic and Atlanta Symphony are on her calendar for the 2024-25 season. Orchestras such as the Gewandhausorchester Leipzig, the Deutsche Kammerphilharmonie Bremen, the Rundfunk-Sinfonieorchester Berlin (RSB), the Orquestra Nacional de España, the Seattle Symphony Orchestra, the Kaohsiung Philharmonic and the Seoul Philharmonic regularly invite Julia Lezhneva and she regularly works with renowned conductors such as Adam Fischer, Giovanni Antonini, Herbert Blomstedt, Emmanuelle Haïm, Paavo Järvi, Vladimir Jurowski and Andrea Marcon.
