I can’t remember if I’ve posted this before or not. It’s the allegro movement of Bach’s Third Brandenburg Concerto. This was the very first piece I ever heard from these guys. It was on KWMU, the local National Proletariat Radio station in St. Louis. I immediately went out and bought the album this was on. I also saw them perform it live a few years later in University City (a St. Louis suburb). I think this is the original lineup, father and three sons. The old man has passed on but his grandchildren are now in the various lineups.
