A fine new period-instrument version from Van Dael and Van Asperen on Naxos goes to the top of the list. It is beautifully played and recorded, and the violinist has a positive relationship with her distinguished keyboard partner. The set gives very great pleasure and satisfaction and includes four alternative movements for BWV 1019.
"There is a welcome flexibility in rhythm, Bach's ornaments played very quickly and slightly before the beat on which they are written. Indeed at times you feel van Dael is adding, with good taste, a slightly rustic atmosphere. The allegro movements are generally taken at a sprightly yet unhurried pace, so that the interplay between the two performers has a remarkable inner clarity. My only reservation comes in the finale of the third sonata, where the interpretation becomes a little too turbulent and aggressive. Elsewhere there is a musicianship that allows the music to emerge unscathed by performance inconsistencies."
