Outside Lands Music Festival wrapped up in San Francisco yesterday, highlighted by a headlining set from Lionel Richie and a pair of sit-ins from longtime collaborators Jason Isbell and Ryan Adams, who were grouped together on a side stage.

Isbell’s set came first, with the singer-songwriter offering up cuts from his latest Something More Than Free and standout Southeastern before welcoming Adams for a closing take on The Rolling Stones’ “Sway” featuring Isbell on vocals with Adams adding guitar.

During Adams’ set, it was Isbell’s time to return the favor as he joined The Shining for “Oh My Sweet Carolina” towards the end of the band’s set. Isbell has joined Adams on the tune before, including in 2015 at the Ryman Auditorium in Nashville where he joined Adams and Natalie Prass on the song.

Watch both performances here.
