The violoncellist Sol Gabetta has become an essential part of the international concert scene. On stage, she seems to perfectly merge with her instrument. The portrait of "A part of my soul" leads us through rehearsals and performances, including works by Elgar, Schumann, Shostakovich, Bloch, Vivaldi and Schubert. Written for Sol Gabetta the world premiere of "Presence" by Pēteris Vasks marks the end of the film about a soloist, who not only impresses the audience with her unique musical touch, but also with her charisma. The audience seems to become part of the concert and of Gabetta’s world of imaginative and emotional perception.
