I stayed in a nice hostel in Venice.
This lady was busking out in a big public area, in Florance, Italsy. Good musician, good gal, good gumption. Good for her! And the audiennce.
There are two videos here - one of Beatriz performing, and the other, just a fragment, of her negotiating with another street musician. She got there first, and thereby gor the prime spot. I later saw him and his group performing in a lesser area.
