Les Six came to the fore in 1920s Paris as acolytes of the iconoclastic Erik Satie and briefly caught the spirit of the age before veering off in diverse directions. This ingenious album of clarinet-piano music from either end of their careers. Francis Poulenc, the most lyrical and the only one with a major opera to his credit, can be heard in sonatas from 1918, 1922 and 1962, the earliest having an absolute earworm of an Andante, the kind of music people hummed as they went off to found new colonies.
