Uncle Earl is an American old-time music group, formed in 2000[1] by KC Groves and Jo Serrapere.

[2] Currently the lineup consists of four women, all of whom share vocal duties: KC Groves, Kristin Andreassen, Abigail Washburn, and Rayna Gellert.

Instead, they wanted to promote a CD with traditional material they had recorded, and put together a small temporary lineup to play a few shows.

The 2003 lineup consisted of KC Groves on mandolin and guitar, Abigail Washburn on banjo, Rayna Gellert on fiddle and Kristin Andreassen, guitarist, fiddler, and clogging.

[7] In 2010, the band announced that Gellert and Washburn had left on amicable terms, and were pursuing other musical projects.

On their website the band mentions Eric Thorin, Sally Truitt, Erin Coats Youngberg, Alana Rocklin, Mary Lucey, Bryn Davies, Laura Cortese, Kyle Kegerreis, Missy Raines, and Dan Rose, with whom they recorded the album She Waits for Night.

Bassist Sharon Gilchrist left the band in early 2005 to play mandolin in the Peter Rowan and Tony Rice Quartet.
