Every July, Southbank Sinfonia – comprising some of the world’s most outstanding young musicians – makes its home at the Anghiari Festival in Tuscany. For a week, orchestral, choral and chamber music abounds from every piazza, church and cloister of this beautiful hill-town overlooking the Tiber valley.
