NPR's Elizabeth Blair reports on the play "And They Lynched Him On A Tree," the controversial work by black American composer William Grant Still and white poet Katherine Garrison Chapin. The work is scored for orchestra and two choruses — a white chorus sings the part of a white mob that lynches a black man; a black chorus portrays his friends and family. The work has seldom been performed as it provokes highly emotional reactions in audiences and performers alike. But a company in New Haven, Connecticut, is performing it in the hopes of bringing the black and white communities there together.
