Violinist Matteo Fedeli will use a different Stradivari for each movement of Piazzolla's Four Seasons of Buenos Aires at a charity concert in Cremona on 2 July. Fedeli will play the c.1730 'Vesuvius' and the 1715 'Cremonese', both of which are owned by the city of Cremona, and the 1695 'Sandars' and the 1703 'King of Prussia', which both belong to a private collection. Also on the programme is Mendelssohn's Concerto in D minor for Violin and Piano. The venue is the Teatro Ponchielli, and the concert is in aid of the Italian Multiple Sclerosis Association.
