Album: Alexander Tharaud, La Boeuf sur le Toit (Virgin Classics)

Pianist Alexandre Tharaud sheds his customary cool to "faire le boeuf" (or "jam") with Frank Braley, Natalie Dessay, Madeleine Peyroux and assorted stars of the Parisian theatre in a programme exploring the legacy of the Jazz Age composer-pianists such as Clément Doucet and Jean Wiéner, whose formidable musical wit is suitably celebrated.

More startling still is "Caramel Mou", created by Jean Cocteau and Darius Milhaud in 1921.
