Whatever use you intended to make this amount, you will find everything! The keyboard works are performed on the harpsichord, which reproduces the authenticity of the music. While the interpretations are not all references of the kind I have not found anything mediocre, but it is true that I have not heard everything. The icing on the box is the complete scores of the works present in these 160CD, scans quite usable if you had any need. So run, you will not regret it!
