Glenn Gould's 1964 recording of the Bach Two- and Three-Part Inventions needs little introduction to collectors, for the simple reason that Sony has reissued it umpteen times on CD. However, this latest incarnation via the label's newly reconstituted Great Performances series yields its fullest-sounding transfer yet. As a result, the piano's infamous middle-register "hiccup" effect that Gould charmingly describes in the booklet note is more pronounced, along with background rumble (the subway?) masked in previous editions.

But what's most important is that Gould divines more character and meaning from the Inventions than many pianists who've looked upon these works as little more than teaching pieces. I especially like how Gould creates a unifying arc by juxtaposing each two-part invention with its three-part counterpart in the same key, sometimes dovetailing non-stop from one piece to the next.

In addition to the aforementioned sonic improvement, Sony includes three unedited takes for the F major, B minor, and F minor Sinfonias that stem from the 1955 Goldberg Variations sessions. Although Gould rejected the recordings, they nevertheless came out on Sony's 2005 deluxe "Birth of a Legend" Goldbergs reissue. Three complete performances of these pieces from the same sessions appear here for the first time. If you've heard Gould's 1955 CBC broadcast of all 15 Sinfonias (CBC PSCD 2005), you'll know to expect more spontaneous and pianistically oriented interpretations than the relatively astringent 1964 remakes. For example, the B minor proves friskier and lighter in touch than the later version, while conversely, the F minor is a little broader, with more melodic inflection and discreet yet ravishing dabs of sustain pedal. God only knows what bells and whistles Sony's next Gould Bach Inventions re-re-re-re-issue may bring. Until then, the present release is the one to get.
