This set features the following works:
1. "Ich habe genug" (BWV 82a)
2. "Mein Herze schwimmt im Blut" (BWV 199)
3. "Jauchzet Gott in allen Landen" (BWV 51)
4. "Ich bin vergn�gt mit meinem Gl�cke" (BWV 84)
5. "Non sa che sia dolore"/Italian Cantata (BWV 209)
6. "Weichet nur, betr�bte Schatten"/Wedding Cantata (BWV 202)
It’s far from complete, but I’d say it’s a pretty good compilation. As for the period instruments, I think you’ll have to look elsewhere. BWV 199 uses a viola da gamba obbligato, but that’s as far as they were willing to go for historical accuracy.
