In the clip above (courtesy of
sanmartinfields) you can see and hear a one movement concerto performed by the
Klaipėda Chamber Orchestra and composed and conducted by
Mindaugas Piečaitis to accompany the piano improvisations of a very clever cat named Nora, whose image at the keyboard is projected above the orchestra as she performs for an apparently appreciative audience of fellow felines. You can read more about this project at the
CATcerto website.
