I'm not ready to review these performances, except to say that they are uniformly brilliant, not all by the same ensembles, and quite a lot more expensive if purchased separately.
The nine operas included on the 27 CDs are:
L'Orlando finto pazzo, RV 727
Juditha triumphans, RV 645
Tito Manlio, RV 738 (currently my favorite)
La verità in cimento, RV 739
Orlando furioso, RV 728
L'Atenaide, RV 702
Il Farnace, RV 711
L'Olimpiade, RV 725
Griselda, RV 718
The 28th disk in the box is a DVD documenting the whole production concept. If you want a preview of the singing quality, I suggest you go to youtube and search for some of the singers - Jaroussky, Piau, Lemieux for starters - and conductor Jean-Cristophe Spinosi.
