Among recorder players, Michala Petri is something of a Holy Grail. She is so very versatile, she could even make the Declaration of Independence sound good if she chose to play it. But Mozart never composed anything for recorders—not even that famous scale in the "Magic Flute". Recorders in the late 18th century were definitely on the way out as the premier woodwind instrument. The four pretty faces on the cover of this CD are an attraction in itself, and the playing beyond cavil. Yet even though Petri sails through the music effortlessly, the recorder sound is thin and strained because the tessitura is so high. Within their normal range, recorders can sound sweet and richly mellow. But they don't like to be pushed.
