Classical Music creates large ,juicy, robust grapes

We are off to Italy again in a few weeks and I am going to be in the Arezzo area for a few days at end of trip.I will be on a mission while in Tuscany.... I am to find a town called Montalcino where there is a vineyard owned by a man who has made a startling discovery and now being studied scientifically. His grapes were not growing as robustly as they should have been for years so he tried an experiment. He decided to pipe classical music to half of his vineyard and the grapes responded by growing hlarger, juicier and redder than those not listening to music... It deserves a closer look so I will try to find it and go there.... Fascinating isn`t it.
