This box met certainly all expectations! First the negative point: it is true that some discs have mediocre quality performances recorded. In my opinion, the Matthew Passion is rather weak due to some soloists, the choir and recording facilities. This is a shame, as it is one of the major Bach works AND there is also a DVD included which is, logically, of the same quality. Having said that, almost everything else is positive: the cantatas are well recorded and directed. Don't expect Gardiner cantatas, these recordings are not always that 'bombastic' if I may say so. Some parts of the cantatas (individual aria's/recitatives/...) are better than others, but this is the case in every collection of cantatas (e.g. Gardiner, Koopman, etc.). The alto may sometimes give problems to be understood well, but that doesn't really annoy me (often). The chamber music part is very nice, a lot of great recordings in there, e.g. the harpsichord concertos. I also like the cello suites played by ter Linden. Keep in mind that the keyboard works are performed on a harpsichord, so if you prefer them played on a (forte)piano you should consider this purchase. Nevertheless, if you buy this box for the cantats only, the price is still in balance. The harpsichord works are generally, from what I heard, nicely performed. Some parts are better than others, but I can't give a final review on this part of the product as I haven't heard enough of them yet. I heard some organ works and they are nice, the sound is very well recorded as well. Of course, everything is a matter of personal taste and expectations. All and all, a very nice price-quality outcome: some recordings are better than others (only few are really low recorded and/or performed), so I would certainly recommend to buy this collection.
