Minnesota Orchestra Assistant Concertmaster Rui Du performs The Butterfly Lovers Violin Concerto, credited jointly to two composers—Chen Gang (b. 1935) and He Zhanhao (b. 1933). Cast in one long movement and subdivided into seven sections, the concerto is a musical representation of the Chinese legend of the Butterfly Lovers, with the solo violin representing the protagonist Zhu Yingtai, and the cello part symbolic of her lover Liang Shanbo.
