I, for one, enjoy this album, unlike the reviewers below. The two stars given to the album by that reviewer were unwarranted; No matter how "incompetent" Kamus thinks Jarrett is on this record, the music itself is worth far more than two stars. I am great fan of Jarrett, jazz and classical music. I myself play both classical and jazz trumpet at a professional level (the latter... my classical training is coming along nicely, however) and have Gould's Goldberg Variations as well as excerpts from others. While Gould whirlwinds the Variations and performs it expertly, one can only find oneself wondering how much of the recording is Gould simply pumping Bach's music up to his level, and how much of it is as Bach intended it. The same goes for most recordings of the Clavier, which are either completely stale and "legit", or the indulgences of the artist are too much. In Jarrett's rendition (not interpretation), we see something almost opposite of what Jazz players are notorious for (completely re-interpretation); Jarrett plays the Clavier in a mellow, graceful mood, taking all the designated tempos and resisting "adding" anything to the music. His touch is apparent though, and any staleness of the music which can be exhibited on other recordings of Clavier are gone here. This is not the exciting, furious Bach of Gould, this is the thoughtful, pleasant Bach of Jarrett, void of any changes or overbearing artistic styles. To me, Jarrett has almost gone and removed the "artist" from the equation; we forget it is Jarrett playing and simply listen to the pleasant polyphonic lines, the singing voices, and the shimmering releases. A wonderful album; I wouldn't recommend it over the Gould recording for people looking for an 'interpretation' of Bach, however, if you simply want the Well-Tempered Clavier as written, played in a lyrical but not-over-indulgent style, this is your bag.
I would also encourage listeners who have deemed Jarrett void of classical ability to check out his Handel suites or Shostakovich Preludes and Fugues op. 87, which are phenomenal.
