Ryan Adams and Emmylou Harris will play a special show on September 29 at the Breese Stevens Field in Madison, WI as the two longtime collaborators join forces once again.

Adams welcomed Harris on his solo debut Heartbreaker as she added vocals to the hit “Oh My Sweet Carolina.” The two have come together over the years to perform the song including in 2011 when Harris joined Adams at his Los Angeles stop.

Adams and his band just wrapped up a lengthy European run with a finale in Berlin and will pick it back up in the U.S. on July 28 with the first of two nights in St. Paul, MN.

Tickets are on sale here.
