Bach's six motets need no introduction. They are arguably the most intricate and fascinating choral pieces ever written, and among the most difficult to perform. Layers upon layers of complex polyphony and counterpoint. Achingly beautiful melody and harmony. This music explodes vertically, horizontally, and seemingly into new dimensions. This is music to listen to deeply and become enveloped by.
And Bach Collegium Japan nails it. With smallish forces (probably no more than two to a part), the lines are clear and intimate -- none of that big choral fuzziness. The recording was made in a location with little reverberation, which contributes to the clarity. The group is balanced, tight, and in tune.
The interpretation is lively and passionate in exactly the "late baroque" sense of those words. This is no academic recording of a museum artifact. This feels like a fresh performance of living and breathing music. Over the past 15 years, Bach Collegium Japan and Massako Suzuki have recorded 45 albums of Bach's cantatas and all of the other major sacred works (Mass in B Minor, the two passions, the oratorios, etc.). At this point, Bach is in their marrow. You really fell that internalization in this recording.
I have recordings of the Motets by RAIS-Kammerchor/Rene Jacobs, La Chappelle Royale/Philippe Herreweghe, The Sixteen/Harry Christophers, Nederlands Kamerkoor/Peter Dijkstra, and the Hilliard Ensemble. While all are very fine, this is the one to get.
