We saw this during a Christmas Holiday Home Tour in New Smyrna Beach. The baby grand had been left behind in the old bungalow-style home and no one in the family wanted it. A local artist works in cement and he gutted the piano, keeping its natural curve, but opening up the middle. Then he made a custom stone-embedded cement countertop for the wine bar. There is an upper and lower counter. The "guts" of the piano are a piece of work in themselves. They mimic the shape of the piano and were hung on the wall going up the stairs.
