More than half a century separates the earliest and the latest of the works here. The C major Trio Sonata was one of Bach's earliest compositions, written at the age of 17 more or less under his father's supervision, and the D major Quartet was composed in the last year of his life, while he was Music Director in Hamburg. The remaining items date from his time at the court of Frederick the Great. The C minor Sonata is extraordinary, a programmatic work 'portraying a conversation between a Sanguineus and a Melancholicus' who disagree throughout the first two movements, but the former's outlook prevails in the finale. The talented Florilegium players bring out to the full the bewilderingly diverse character of this sonata.
If the Sonata for unaccompanied flute was written for Frederick, as seems likely, he must have been quite skilled, able to cope with some virtuoso passagework. Ashley Solomon's performance is most persuasive. How far Carl Philipp developed is shown by the late quartet, an attractive composition which, besides promoting the keyboard (fortepiano here) from a mere continuo to prominent solo status, is already in the style of the Viennese classics in form, and links the first two movements. The whole disc is strongly recommended.
