If you have any doubt that the fipple flute is an acceptable substitute for the specified transverse one in these works, this recording could allay it. What is lost is the warm, intimate, breathy, pitch-bending sound of the minimally-keyed wooden instrument, but what is gained is the luculent clarity and (in Petri's hands) spot-on accuracy of the recorder. Instruments at period pitch (which for her own good reasons Petri does not use) would restore some of the warmth, but rarely can you have everything—and here you have so much to be grateful for.
Jazz pianist Keith Jarrett has recorded Bach before, on both piano and harpsichord. His interpretations are not jazz versions of Bach but are played straight. In this case you might say relatively straight, for Bach's sonatas for violin and keyboard, BWV 1014-1019, were written for a harpsichord and are generally played that way; somehow the ear is jarred more by the piano here than in Bach's solo keyboard music (which Jarrett has also recorded). Jarrett fans will find the evidence of his characteristic style not in rhythmic inflections toward jazz but in his way of sustaining notes, which is never excessive.
Two of vibraphonist Gary Burton's albums from 1969-1970 are reissued in full on this single CD. Burton teams up with pianist Keith Jarrett for five numbers (including four of Jarrett's originals) in 1970, using a quintet that also features guitarist Sam Brown, bassist Steve Swallow, and drummer Bill Goodwin. The other session has more of an avant-country flavor, with Burton, Swallow, and Goodwin joined by guitarist Jerry Hahn and violinist Richard Greene; Michael Gibbs and Swallow contributed most of the obscurities. Burton was at his most explorative during this period, which is why he can be considered one of the pioneers of fusion (although his music never really fit into a tight category). This is excellent music that mostly still sounds fresh.
