Community MusicWorks celebrates summer in the city in all its glorious contradiction: bustling commutes and quiet afternoons in the park; clangorous sounds from the world at large and quiet, inner rhythms; solitude in the midst of a crowd. It’s all here, via four glittering musical portraits: Hannah Kendall’s Citygates and Leoš Janáček's Idyll, Jessie Montgomery’s Strum and Steve Reich’s Duet.
