At the mid-point of this series of 15 weekly programmes, Christopher Hogwood pauses in his historical and geographical account of trio-sonata form to introduce a programme of sonatas from several countries featuring wind instruments. A newly-reconstructed sonata for two recorders by Handel, a work formerly attributed to Handel, and sonatas by William Cor bett, Telemann and Vivaldi are played by members of the ACADEMY OF ANCIENT music.
