Mendelssohn was struck by the rugged landscape of Scotland during a walking tour there, and later infused his Third Symphony with hints of Scottish dances and reminiscences of the countryside. Helen Grime’s Violin Concerto is a study in contrasts—from the frenzy of wild virtuosity to sensitive, reflective melodies—and is played here by Leila Josefowicz, a leading performer of new music for the violin. Conductor and composer Daníel Bjarnason begins with one of his own pieces, inspired by the energy and brightness of the Pacific Ocean.
