A tight, funky clavinet groove from John Paul Jones drives 'Trampled Under Foot', one of the most rhythmic songs in Led Zeppelin's repertoire, taken from the double album Physical Graffiti from 1975. In the tradition of old blues, Robert Plant reaches for car metaphors as imagery for desire. The B-side is 'Black Country Woman', an acoustically tinged song from the same album. This edition is a 7-inch single with a die-cut sleeve, released for Record Store Day Black Friday.
