'60s Motown rarely strayed from that classic sound, but this one attempts an earthier, Muscle Shoals/Stax-like sound -- with brilliant results. Martha's voice could even be mistaken for Aretha here. An underrated, mighty danceable single with killer rhythmic guitars, tambourines and a bubbling bassline.

Great funk/soul track with a healthy dose of political and social commentary circa 1970 set to a killer bass line - it's scary how much of it is still relevant today. "A ball of confusion, that's what the world is today..."
