Brooklyn’s music scene is known for its indie outfits, electronica and synthesizers, but for one evening, Sept. 22, local musicians are bringing out their banjos and fiddles for a Bluegrass Bash at The Bell House. Musicians spanning several generations are coming together for a good cause–raising funds for the restoration of the historic Old First Reformed Church a few blocks away on Carroll Street. The house of worship was originally built by Peter Stuyvesant in 1654 and now serves as a homeless shelter, day care and community space for local art groups. Tonight’s the night to see some of the borough’s best and brightest bluegrass musicians (there’s more than you’d guess) all perform together on one stage to collect donations for a new ceiling for the church, so come stomp your feet and literally help them raise the roof.
