"I have owned dozens of CDs with the BWV 21 Cantata, and this unassuming looking CD has by far the best choral treatment. The choirboy alto is marvellous, especially in the aria Seufzer Tranen Kummer Not. This part was written for a boy to sing, not a woman. And after listening to many operatic, stilted performances of this piece, with women soloists, the real jewel of them all is this recording. It is hard to believe something this perfect was originally part of a low-price set. The other recordings on this CD are excellent too, but listen to the Seufzer Tranen Kummer Not. WOW!!!"
