Give me wings : how a choir of former slaves took on the world

The story of the "Jubilee Singers, [who] traveled from Cincinnati to New York, following the path of the Underground Railroad. With every performance they endangered their lives and those of the people helping them, but they also broke down barriers between blacks and whites, lifted spirits, and even helped influence modern American music: the Jubilees were the first to introduce spirituals outside their black communities [and are still active and highly regarded today]"--Amazon.com.
