If you thought you’d seen all the best live music last week during a certain festival, think again. Grammy Award-winning singer-songwriter Patty Griffin is joining fellow artists Sara Watkins and Anaïs Mitchell for this special singers-in-the-round performance. She’s on tour following the release of her extraordinary new album “Servant of Love,” which has already received critical praise.

Watkins is also a singer-songwriter and a founding member of the progressive bluegrass group Nickel Creek, while Mitchell, who focuses more on narrative folksong, poetry and balladry, is developing her folk-opera album “Hadestown” into a full stage production.
