In the second set they invited a series of guest stars up to play with them, including singer Jen Larson who frequently shares a stage with them, and also Trip Henderson, Ben Fraker, Elena Skye, the Sheriff of Good Times, and me. It was great fun and a great honor to play with them and a wonderful night overall.
Boo is a well-known country guitarist who's played with Opry stars and won Grammies, and along with his partner Elena Skye runs the Demolition String Band, a great NYC roots outfit. Bob was a founding member of the Wretched Refuse String Band and an original member of the Andy Statman Klezmer Orchestra, and repairs/restores guitars for most of the East Coast's bluegrass/old-time musicians.
They play fairly often in Brooklyn, so keep an eye out for them.
