Adding a guest-soloist to the program can be done in two ways:

- Presenter can suggest and then, upon getting confirmation from Maestro Rachlevsky, engage a soloist. It can be an international star or a local performer – many such collaborations in the past tours resulted in excellent, memorable performances. All financial arrangements and logistics for engagement of a soloist under this scheme are strictly between the Presenter and the soloist (or his/her agent).

- Maestro Rachlevsky can suggest a soloist, who has performed with Chamber Orchestra Kremlin or is otherwise well familiar to him. Once again, the range is from a young performer to an established master to an international star.
