Madrid Street Musicians

The street musicians in Madrid are generally of very high caliber. Someone told me the other day--I don't remember who--that the street musicians in major European cities are often required to go through auditions to get a permit to perform. They are rarely slouches in the main tourist areas. These guys, a father, his two sons, and maybe a brother or cousin were astoundingly great. They were whipping out highly-arranged, technically-difficult classical pieces on hammer dulicmers with accordian and bass with nary a sour note.
