They're performing at the Washington Folk Festival, Glen Echo Park, Glen Echo Maryland, Saturday, June 5th at 2:00 p.m. in the Adventure Theatre.
It's a wonderful festival, and FREE. I'm not entirely disinterested about publicizing this event--I'm on the programming committee and hosting/performing in a workshop on vocal styles. Bill D and Ferrara are involved with crafts, and Ferrara will be singing. SongBob also performs as part of Sidekicks (with LaMarca's husband). I'm probably missing other performing Mudcatters. All the performers are from the greater DC area.
