The "Butterfly Lovers" Violin Concerto arrangement for piano concerto is adapted from Chen Gang who is a famous musician and educator in China. "Butterfly Lovers" is a love story known to every Chinese. From violin to piano, music is a kind of "transformation," rather than simple repetition. The arrangement gives piano, the giant "king of instruments", a brand-new role in the story of "Butterfly Lovers", which gave birth to a unique version and a new story-telling approach.
