Leonhardt's thesis that the Art of Fugue is, like the Well-Tempered Clavier, music for stringed keyboard instruments is convincingly demonstrated here. The mirror fugues in particular are most musically presented.
A mezmerizing rendition dreamily played on a period harpsichord. I prefer strong, uplifting performances instead of Leonhardt's flaccid interpretation.
This is a particularly interesting (and very beautiful) recording as it is the first ever recording of the Art of Fugue on any keyboard. The recording is beautifully close, which enables you to hear the different voices with great clarity. A classic recording; should be listened more to.
