Bach´s flute sonatas are not new repertoire, of course; they´ve been widely interpreted in a variety of presentations. But the fact that the recorder virtuoso Michala Petri has turned her attention to them (again, following her widely-praised 1992 recording alongside Keith Jarrett, without a cello or gamba player) is certainly good news. And this time she brought along harpsichordist Mahan Esfahani and viola da gamba player Hille Perl, filling out the sound nicely. As always, Petri´s playing is exceptionally lovely, and she manage to shed new light on these evergreen works-partly through the harder timbre of the recorder, and partly through her own knowledge and love of Bach´s music.
