Due to a family emergency, Yonder Mountain String Band guitarist Adam Aijala sat out his band’s shows at Knoxville, TN’s Tennessee Theater and Charlottesville, VA’s Jefferson Theater on Saturday and Sunday, respectively. In a post on their Facebook page, the band confirmed that Infamous Stringdusters’ Andy Falco would sub for Aijala in Knoxville while local-area guitarist Larry Keel would perform with the group in Charlottesville. Not only did Falco perform with Yonder throughout their set on Saturday but the rest of his band—who also opened the show—emerged at various points as well. During Yonder’s first set, Stringdusters bassist Travis Book—who subbed for Yonder’s Ben Kauffmann earlier in the tour when he left to be with his wife and newborn—emerged for “Kentucky Mandolin.” Soon after, Stringdusters’ fiddler Jeremy Garrett stepping for both “Cuckoo’s Nest” and “Two Hits & The Joint Turned Brown” at the end of the group’s show.

During Yonder’s second set, Stringdusters banjoist Chris Pandolfi got in the action on “Death Trip” and, at the end of the set, dobro player Andy Hall emerged for a segue from “Up On The Hill Where They Do The Boogie” into “King Ebeneezer” and “Raleigh & Spencer.” All the members of Infamous Stringduster then took the stage with Yonder for the join encore of “Come Together” and “Shady Grove.” Both groups will perform at Lexington, KY’s Buster’s this Wednesday, February 29.
