Theremin and piano meet in one evening, where electric vibrations of air intertwine with the live intonation of the piano. The program gathers rare compositions, premieres, and improvisations, turning the concert into an experiment with the familiar sound of academic music. At the center of this concert is the theremin, an instrument surrounded by many legends.

The theremin in these pages becomes a conduit into a space where emotions are colored by mechanical precision and at the same time touching fragility. In the second part of the concert, the focus shifts to a more recent time.

Peter Theremin's own compositions connect family history with experimentation in sound: the use of a contactless controller and electronics emphasizes how far the development of the instrument has come from its early performances. The piece zhokhowsky for theremin and piano adds another perspective to this series, connecting a minimalist gesture with a gradual build-up of tension. The final improvisational set by Peter Theremin and German Markhasin transforms the
