Ready, Set, Accordion! Yes, it's international Accordion Awareness Month. To mark the occasion, we'll head to Rome to hear Alberto Fantino in concert with pianist Antonio Valentino. The music is by Astor Piazzolla, called "Libertango." And then it's off to the National Gallery of Art in Washington for a dose of Norwegian folk dances, arranged for the accordion and played by Norway native Geir Draugsvoll.
