Rumbustious and playful, Francis Poulenc is deemed a lesser figure among the greats of 20th-century music but it's a mistake to underestimate him. His work is no mere froth; there's a smoky, autumnal sadness to his harmonic writing, a lingering regret beneath the joie de vivre, particularly in the intimacy of his chamber music. The London Conchord Ensemble understand this completely, working their magic in the bittersweet sonatas for piano and cello, violin, flute, oboe and clarinet, and romping through ensemble works large and small, including his Elégie for horn and piano (written in memory of Dennis Brain) and the irrepressibly gorgeous trio for piano, oboe and bassoon.
