On September 21 in Bari , the orchestra of Teatro Petruzzelli will perform the world premiere of Fabio Vacchi's Triplo Concerto for two flutes and harp. The piece, which was commissioned by the theatre, strengthens the tie that the composer has had with the house since April 2011, when it hosted the world premiere of his opera Lo stesso mare (The Same Sea), drawn from the novel of the same name by Amos Oz. The soloists will be Giampaolo Pretto, Manuel Zurria and Patrizia Radici and the performance will be conducted by Renato Rivolta.
