Patty Griffin

Previously unheard duet was recorded several years ago.

Album marks her first new music in four years and includes backing vocals by Led Zeppelin singer on two tracks.

Singer discusses his past and future - and veers away from doing Led Zeppelin a “disservice” with another reunion.

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 first single from Patty Griffin's new album 'American Kid' features Led Zeppelin lead singer Robert Plant on harmonies. 'Ohio,' is much more than a vocal collaboration between the two however. Griffin credits her longtime partner with bringing the track to its final resting place.
