Since touching Bach cantatas, I found some aren't popular to get notice but still being with its characters. Ex in this disc of NO.147, I found how beautiful it's the instrumental part, ex organ. Of course I guess maybe Koopman was a excellent organ player so that did this outstanding.
However, I post this example is to express bach's cantatas were all valuable treasuries, comparied to other cantatas I had listenned. They gave us mood more peacefully to enjoy silently.
Besides, in Koopmann's set, signers always performed excellently to balance with music, that's why I think it's worth recommanding, at least I am never disappointed in this set.
