Virginia-based Robin and Linda Williams are known for their rich harmonies and original songwriting rooted in the country/bluegrass/gospel tradition. Enjoying widespread national prominence on Garrison Keillor’s “A Prairie Home Companion” (including performing in the Robert Altman film of the same name), Robin and Linda Williams are said to create music that is both comfortable and thoughtful, which has enabled them to keep an even keel while musical trends come and go.
