Young French composer Bruno Mantovani studied with Boulez at Ircam before embarking on his meteoric rise. Recorded with piercing clarity, this selection of pieces performed by various combinations of pianist Claire Désert and the Trio Wanderer reveals certain distinctive tropes, notably a liking for repetitive trills and throbbing rhythmic pulses, contrasted in his inward-looking, almost solipsistic piano sonata “Suonare” with a more contemplative counterpoint.

Just as his Little Match Girl Passion employed a palimpsest of Bach texts, so David Lang’s five-song suite Death Speaks derives directly from Schubert lieder, reconstituting proclamations in a manner which allows Death to talk directly to us in a variety of guises all sung in a fittingly pale, deathly timbre by Shara Worden over delicately dramatic settings of guitar, piano and violin produced by The National’s Bryce Dessner.

First produced in 1931, a couple of years before Hitler came to power, Carl Zuckmayer's comedy pokes risky, spirited and oddly charming fun at the German inclination towards militaristic conformity.
