Nikolai Kapustin Sonata for flute and piano, Op125. This work, to date Kapustin's only composition for flute and piano, was written in 2004 at the request of Immanuel Davis, flute professor at the University of Minnesota. The work is in four movements, and both flautist and pianist are occupied, jointly and individually, in performing a piece that requires a considerable level of technique as well as a thorough grasp of Kapustin’s jazz idioms.
