If you ever have a chance to stop by the Old Stone House in Washington Park in Park Slope, Brooklyn, it is worth the visit. This reconstructed house dates from 1699 and played a key role in the American Revolution and the Battle of Brooklyn. If you are lucky enough to be there when The Good Coffee House music series is going on, even better! Frank and Nancy Moccaldi (talented musicians themselves) curate a terrific series of musicians from many traditions, including folk, blues and bluegrass. Last night a lucky few of us turned up at a special Good Coffee House performance at the Brooklyn Society for Ethical Culture to hear The Feinberg Brothers. They are a traditional bluegrass duo from Long Island, New York, fronted by brothers Rourke and Patrick (with father Ron Feinberg — a member of Straight Drive — on vocals and guitar as well.) They put on an exceptional evening of music, and they are among the best young bluegrass musicians in the Northeast. If you ever get the chance to catch one of their shows, I urge you to go. And you should go to Facebook to find The Good Coffee House page so you can write the upcoming concerts in your calendar. You do not want to miss this gem of a music series. You can thank me later.
