The Soggy Bottom Boys are a fictional band invented for a movie, the Coen Brothers’ 2000 “O Brother, Where Art Thou?” The band was so fictional that the faces on the screen didn’t even make the music: Dan Tyminski sang actor George Clooney’s vocals, and the instrumental picking was provided by Tyminski and his Nashville bluegrass pals.

Those musicians finally performed in the real world as their fictional counterparts in 2014. Now three members of Alison Krauss & Union Station (Tyminski, Barry Bales and Ron Block) will be joined by three members of the Nashville Bluegrass Band (Stuart Duncan, Mike Compton and Pat Enright) for their first full-fledged tour as the Soggy Bottom Boys, which heads up the East Coast to the Birchmere this weekend. They’ll perform the soundtrack songs plus other tunes in the same style as a 1930s, pre-bluegrass, old-time country band.

But if the Soggy Bottom Boys had been real hillbilly stars, as the movie suggests, their careers wouldn’t have stopped in 1937. They would have moved to Nashville in the 1940s, added a pedal-steel guitar and performed their No. 1 honky-tonk hit, “Doing the Dog ’Cause You’re Acting the Cat,” on the Grand Ole Opry in 1947. Maybe they would have bought some Telecaster guitars, grown their hair long and cut the very first rockabilly single, “Dipsy Do, Dixie Don’t,” in 1953. That’s the music we want to hear from the Soggy Bottom Boys on their next tour.
