On its latest release, the Nash Ensemble—celebrating its 50th anniversary next season—performs music by a variety of film/stage composers, including Herrmann, Franz Waxman, Aaron Copland and the granddaddy of them all, George Gershwin … The six-piece British ensemble, led by pianist/conductor Ian Brown, is known for its eclectic repertoire. Here it ably captures the windswept vistas in Herrmann's lushly romantic clarinet quintet Souvenirs de voyage (1967). … But you can't beat Gershwin's jazz-infused Lullaby, which wafts through the air, evoking the gentle night strains of Tin Pan Alley.
