What role should art play in society, and who's to say? These are just two of the questions Julian Barnes ponders in his slim but by no means slight new novel, which chronicles the tribulations of Russian composer Dmitri Shostakovich during his decades under the successive thumbs of Stalin and Khrushchev. Like his Booker Prize-winning The Sense of An Ending (2011), The Noise of Time is another brilliant thought-provoker which explores the costs of compromise and how much confrontation and concession a man and his conscience can endure.

Stephen Steinbrink's unfussy imagery stays detached from meaning. That's part of what makes his seven albums worth your time: In their lushly arranged pop songs, the listener can tie and untie Steinbrink's vivid and unrelated images into something meaningful — or not.
