Query: Great pacing, but with organ?

What a lovely performance. Harry Christophers found a lovely pace at which to perform this most beautiful mass. Unfortunately, however, the recording features instrumental accompaniment in the polyphony. While this tends to not be too noticeable, there are several key moments in the music (where individual voices are isolated) where the organ is quite prominent.This mass needs no accompaniment - the ensemble should not need filling-in by additional instruments.That said, it is far from the typical plodding recording that most labels have published and, as such, is a very worthwhile addition to any period library.
