Last month we learned that Robert Plant was slated to sing on three tracks on folk singer Patty Griffin's new album, 'American Kid.' Today (April 23), Griffin released the video for the first of these duets, 'Ohio.'

The video was directed and designed by Roy Taylor. The clip, in which both Griffin and Plant appear, features scenery made from cut paper and a storyline that dates back to pre-Civil War times.

"I wanted to portray the overwhelming desire to reunite with family and loved ones and the spirit of those who helped," Griffin said. "Visuals were inspired by historical images such as the false bottom wagon, the stairway from the banks of the Ohio River leading to a safe house of [the abolitionist] John Rankin and a lantern hoisted up a flagpole to signal that bounty hunters and their dogs were not in the area."

'American Kid' will be released May 7. Yesterday, Plant announced a summer U.S. tour with his new genre-bending project, the Sensational Space Shifters.
