It does help to hear this music gloriously performed in period style with the chamber ensemble, the authentic stringed instruments, and vocalists in the original manner, without much vibrato.
Charpentier had a great inventiveness, as this music attests. I won't go into much detail here except to say that along with Rameau, there is a real sweetness to his vocal works, when performed in the proper, period-specific style. And these are impeccable, moving renditions. Charpentier may not have always had the courtly pomp of Lully, but in my opinion he is all the better for it.
The result is one happy reviewer. Me. If you have an interest in the period as it played out in France, you should make a point of hearing this disk.
