The semi-historical piece of fiction is modeled more after the Supremes than Martha Reeves & the Vandellas, but it offers a look at the environment and culture of Motown.
Standing in the Shadows of Motown (2002)
This documentary explores the self-named "Funk Brothers," the studio musicians who backed up the artists at Motown, eventually being part of more number one hits than any other musician or band. Archival footage and interviews are interspersed to provide a fascinating portrait of this era in American music.
