Very different fare arrived with the world premiere of Avner Dorman’s “Double Concerto”, in which the temperaments of solo violin and cello were deliberately pitted against and then harmonised with the rest of the orchestra. Benjamin Northey steered brilliant performances by Zukerman on violin and Amanda Forsyth on cello. For the record, Zukerman was all in black and Forsyth in a fiery Chinese red dress, a contrast that added a bit more theatre to moments when their instruments spoke quite differently with each other and the orchestra.
