Bach: The Art of Fugue
Bach never specified what instrument or instruments he wantedThe Art of  Fugueplayed on; nor did he finish it. Fretwork, a group of six superb viol  players, leave the work incomplete, stopping in mid-phrase--the effect is persuasive rather than unsatisfying. The sound of the six different-sized viols is just right for listening to the way Bach intermingles the multiple lines through and around one another--we can learn what counterpoint is just by listening to this CD. Some find the work severe and difficult, and played on a single instrument, like a harpsichord, it can be. But Fretwork manage to vary their tones sufficiently to turn the work into entertainment, albeit intellectual entertainment. You may not come away humming, but you'll be fascinated.--Robert Levine
