After about half a dozen years in limbo, Ton Koopman's marvelous 1983 readings with the Amsterdam Baroque Orchestra are back on the shelf at mid-price, though still on two single discs. The accent in these elegant, flowing performances is on variety--in the texture, in the ornamentation, and in matters of phrasing and articulation. The executants' voicing of the counterpoint is quite effective, as is their pointing of rhythm, which underscores the fact that so much of this music comes from the dance. Erato's sound is quite appealing, though the discs have been mastered at a rather high level.
