Kennedy, the violinist formerly known as Nigel Kennedy, has a well-earned reputation as the bad boy of classical music. His defiantly anti-Establishment antics anger traditionalists and tickle the rebellious. This venture into the Bach canon will confirm both camps in their views. Traditionalists will fume at such excesses as the exaggerated, ugly flourish at the end of the E Major Concerto and the supersonic speeds adopted for the Allegro movement of the two-violin Concerto among much else, including the puzzle-booklet more appropriate to a pop release. Kennedy's fans, though, will relish those elements of what is an ultimately fairly straightforward set of Bach interpretations enlivened by personal touches, a string sound that owes much to "authentic instrument" practices, and zippy speeds that make for exciting listening. Bachians won't be swerved from their allegiance to their favorite recordings of this repertory, among them Grumiaux's humane, traditional approach and Manze's freewheeling period performances. --Dan Davis
