"Brothers and Sisters" is not the name of a singing group; it is more along the lines of an ideal. This feature-length concert film was lensed during the 1972 Black Exposition in Chicago. What we have here, quite simply, is a spectacular display of the finest African-American pop-music talent of the era. Highlight performers include The Jackson 5 (with Michael, of course), Roberta Flack, Marvin Gaye, Isaac Hayes and Gladys Knight. Brothers and Sisters in Concert was directed by Stan Lathan, who later helmed such ethnically-oriented subjects as Almos' a Man (1974), The Sky is Gray (1980) and Beat Street (1984).
