Born in Moscow into a family of professional musicians and having Vladimir Horowitz as her biggest inspiration, Anastasia Voltchok moved to Switzerland at the age of 15 after having become a finalist at the Gesa Anda competition in Zürich in 1993. She then joined the class of Rudolf Buchbinder at Basel Academy of Music. A mix of traditions of the Viennese and Russian piano schools until this day distinguish Voltchok's fiery and sophisticated interpretations of the known and lesser played jewels of piano repertore.

​

Versatile artist and life-affirming woman, honoured with a Gold Medal at the World Piano competition in Cincinnati in 2003, Voltchok began her piano journey at the age of four at the Gnessin School, continued at the Tchaikovsky Conservatory College with her critically acclaimed mother, Prof. Larissa Dedova, at Rowan University of New Jersey with the distinguished student of Abbey Simon, Veda Zuponcic, and finally completed her studies at the University of Maryland with Santiago Rodriguez earning a Doctor of Musical Arts degree in 2003.

​

Since her orchestral debut with Haydn piano concerto at the age eight, Anastasia Voltchok has performed extensively throughout Western and Eastern Europe and the USA. Among her renowned colleagues on stage are Martha Argerich, Lahav Shani, Renaud Capuçon, Dennis Russell Davies, Howard Griffiths, Markus Poschner, Maxim Rysanov, Oleg Kaskiv, Simon Gaudenz, Daria Scarano and Alexei Volodin. As a recitalist she regularly appears at Tonhalle Zürich, Santa Cecilia in Rome and Victoria Hall in Geneva. A guest artist at La Roque d’Anthéron Piano Festival in France, Grafenegg Festival in Austria, Voltchok often paints while on tour, exhibiting her work in galleries around Europe and the wider world.

For Voltchok, visual art is another essential means of expression, because it expands her sensorial connection with the audience. Unlike music, Voltchok notes that art can be “seen by the eye or touched" , for her it is of great importance to “express the energy and the emotion of the moment.” Her recent "Masterful Mind" Art Award of the Circle Foundation for Arts was given to Voltchok for her oil painting "Dream" in January 2025.

Past tours include appearances with Kremerata Baltica and Gidon Kremer, München Philharmonic with Lahav Shani, Kiyv Chamber Orchestra and Roman Kofmann, Vilnius Chamber Orchestra with Adria Cepajte, Mariinsky Orchestra and Valery Gergiev, with Hamburger Symphoniker, Jenner Philharmonie, Bamberger Symphoniker, performances at the Auditorium de Teneriffe, and Lincoln Centre, in New York. Her wide repertoire include works by Igor Stravinsky, M. Weinberg and Richard Addinssell among others, next to the "best sellers" such as Tchaikovsky concerto no. 1, first time performed by Voltchok in 2003 with the Mariinsky Orchestra and Valery Gergiev at the Arturo Beneddti Michelangelo Festival in Bergamo and Brescia, Italy.

In 2016 Anastasia Voltchok founded the “Stars at the Rhine”  Music Festival in Basel, Switzerland, its main focus is the promotion of young artists. The recent editions featured the Swiss premiere of Evgeny Kissin string quartet and a Concerto competition for young performers in collaboration with the Soloists of the Menuhin International Academy, recital of violinist Bohdan Luts and collaboration with bass Michael Leibundgut. In 2022 Voltchok had the idea to widen her organisational skills and created a new festival "Primeurs Musicales" together with her childhood schoolmate, Irina Chcourindina. The aim of this new jewel is to promote some of the youngest performers of Switzerland in concerts in the fun ambience at the the halls and scenic "landschaften" of the Geneva region.

Anastasia Voltchok has recorded for Novalis, Genuin and Solo Musica labels. A recording of Richard Addinsell’s Warsaw Concerto with the Branderburgische Philharmonie and Howard Griffiths was released with label CPO. Her most recent CD "From Partita to Visions" with selected piano works by M. Mussorgsky, S. Prokofiev, J.S. Bach and F. Liszt was released in October 2023 with the Centaur Records in the USA.
