“Black Sabbath” is the soundtrack to a rarely told American story. It is the first compilation ever to showcase legendary African-American artists covering Jewish songs. Focusing on the 1930s through the 1960s and featuring music by Aretha Franklin, Lena Horne, Cab Calloway, and many others, Black Sabbath explores the myriad ways that Jews and African-Americans have struggled against each other and struggled alongside each other.
